The "Soccer City" stadium, officially known as FNB Stadium, is located in Johannesburg, South Africa. It hosted the final match of the 2010 FIFA World Cup, where Spain defeated the Netherlands to lift the trophy.

Asika Sugar Factory is the first sugar factory in Asia, established in 1824. The plant is located in Asika town.

From the final arrangement, we get T faces Q.
Hence, Option C is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

184381483287848568784186

There are four such 8's which are followed by even number and preceded by an odd number.

From the final arrangement, we get ‘A’ is exactly behind of P, so if exchanges its position with O, then A will sit exactly behind of O.
Hence, Option D is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.
​​​​​​​
Case 2: We get the final arrangement as below:

Given number -        8 3 7 9 1 2

Descending order -  9 8 7 3 2 1

Hence, the position of only one digit, i.e. 7 remains unchanged.

School is a place designed to provide an adequate learning environment. In school, the opportunity a child gets to learn affects his cognitive development. The more opportunities a child gets, the better his cognition because he/she will be able to add to his/her mental capacities by learning through these opportunities. In school, during teaching-learning, many new concepts form, many new ideas develop, and many other mental processes take place.

Student-Centered Learning, also known as learner-centered education, broadly encompasses methods of teaching that require learners to actively construct their own knowledge and puts the responsibility for learning on them. 

Inclusive Education:

• It refers to an education system that accommodates all children regardless of their physical, intellectual, social, emotional, linguistic, or other conditions.
• It provides a provision to include disabled children along with normal children in a regular classroom environment.

An inclusive classroom refers to an education system that includes children regardless of physical, intellectual, social, linguistic, or other differently-abled conditions.

• In an inclusive classroom with diverse learners, cooperative learning, and peer-tutoring is actively promoted to facilitate peer-acceptance.
  • Cooperative learning: It refers to a heterogeneous group where students work collaboratively to achieve learning outcomes. It develops critical thinking, brainstorming, communication, and life long learning skills.
  • Peer tutoring: It refers to the learning process where fellow students teach each other. In this strategy, a higher-performing student is paired with a lower performing student to teach specific skills.
• An inclusive classroom is not limited to children with a disability but also gifted children, economically disadvantaged children, children from remote populations, children belonging to ethnic, linguistic, or cultural minorities, or children from other marginalized groups.

Therefore, Social skills development can become a positive strength for normal children in inclusive classrooms.

Inclusive education is where all the students are placed together in age-appropriate general education classes irrespective of any challenges they have. So, students with disabilities receive an education with their peers without disabilities, or we can say, student differences are accepted. So, an inclusive school is committed to improving the learning outcomes of all students irrespective of their capabilities. This special education as a system of education in India began way back in the 1880s.
Hence, the correct answer is, 'is committed to improving the learning outcomes of all students irrespective of their capabilities'.

All India Council of Elementary Education was established by the government of India and was responsible for looking after the development and working of elementary education. In order to accelerate the pace of expansion of elementary education and to fulfill the directive of Article 45 of the Constitution, the Government of India decided that an All-India Council of Elementary Education should be established with effect from July 1, 1957.

Inclusive education refers to the practice of educating students with special needs in regular classes for all. It provides a provision to include disabled children along with normal children in a regular classroom environment.

Key Points

• The primary objective of inclusive education is to educate disabled students in the regular classroom and still meet their individual needs. 
• Inclusive education allows children with special needs to receive a free and appropriate education along with non-disabled students in the regular classroom.
• Students with specific learning difficulties may require resource support for meeting their individual needs.
• This support can be provided in the form of developing specific learning objectives based on an analysis of each student's learning strengths and weaknesses during their class or after school hours or if possible, in another small room during school hours.
• The support can be provided on a one-to-one basis or in a small group.

Therefore, a teacher can address the needs of specially-abled learners in an inclusive classroom by developing specific learning objectives based on an analysis of each student's learning strengths and weaknesses.

If a student does a mistake in language comprehensive-type questions, the teacher would provide appropriate questions with solutions and discuss the mistakes in detail.

In the aqueous solution of Pd(NH₃)₂CI₂, the atoms of chlorine I are in coordination sphere and the van't Hoff factor of the ] compound are unite.

Based on electro chemical series, oxidising power of
F₂ > Cl₂ > Br₂ > I₂

On passing Cl₂ in to a solution containing KF, Kl and KBr,
2KBr + Cl₂ → 2KCI + Br₂ (orange)
2KI + Cl₂ → 2KCI + l₂ (violet)
2KI + Br₂ → 2KBr + l₂ (violet)
Br₂ formed also oxidises Kl to l₂ (violet)

Photosynthesis occurs in two phases-light reaction and dark reaction. During light reaction water undergoes photolysis releasing oxygen and reduced NADPH2 and ATP molecules are synthesized. During the dark reaction, NADPH2 and ATP are used to reduce carbon dioxide into sugars.

The mitochondrion is not a component of a chloroplast. Chloroplasts, the site of photosynthesis in plant cells, contain thylakoids, stroma, and grana as their main components. Mitochondria are separate organelles responsible for cellular respiration.

• In chloroplast, chlorophyll-a is more than chlorophyll b.
• They are not present in equal proportion. Since chlorophyll-a is the main chief pigment in photosynthesis, it is more in number.
• Chlorophyll b is less in number since it is only an accessory pigment.

• Prothallus is a free-living, mostly photosynthetic thalloid gametophyte.
• It is formed during the life cycle of Pteridophyte.
• The pteridophyte is a sporophyte i.e. the main plant body is diploid
• These spores formed inside the sporangia which are borne on the sporophylls.
• The germination of spores is exosporic i.e. in the soil.
• These spores germinate to form the gametophyte which is haploid.
• The gametophyte formed is called prothallus and it is independent as the germination took place outside the sporophyte body in the soil.
• Prothallus male and female sex organs are called antheridia and archegonia, respectively.
• Water is required for the transfer of antherozoids – the male gametes released from the antheridia to the mouth of the archegonium.
• Fusion of the male gamete with the egg present in the archegonium results in the formation of a zygote.
• The zygote thereafter produces a multicellular well-differentiated sporophyte which is the dominant phase of the pteridophytes.
• The sporophytic plant undergoes meiosis to form haploid spores.
• Haploid spores divide by mitosis to form a haploid gametophyte once again. 

So, the correct answer is option 3, A gametophyte-free living structure formed in pteridophytes.

Frederick Frost Blackman proposed the law of limiting factors. Blackman proposed this law in 1905 according to which, a chemical process depends on multiple factors the rate of the process will be limited by the pace of the slowest factor or limiting factor.

Cytokinin is of different types. The cytokinin shown above is of kinetin which promotes cell division. It was isolated by Miller and Skoog from autoclaved herring sperm DNA.

Age pyramid of expanding population is broader at base and thin upwards. Number of individuals in pre-reproductive age is more than post reproductive age. Population size is technically called as population density.

Aristotle contributed to the classification of living organisms by using simple morphological characters to categorize plants into trees, shrubs, and herbs. He also divided animals based on whether they had red blood or not. This was an early attempt at a more scientific basis for classification, although it wasn't as comprehensive as later systems.

• Phytochromes are pigment molecules that act as photoreceptors and are found in plants.
• Enzymes are biocatalysts that cause a change in the rate of a chemical reaction.
• Chloroplasts are cell organelles that are present mostly in plant cells and help capture sunlight and in photosynthesis.
• Proteins are biomolecules formed of long amino acid chains that are necessary for a cell to function.
• Proteins are involved in carrying out nearly all the functions of a cell.

• The body of Euglena is covered by a plasma membrane followed by periplast or pellicle. At the place of union of the two branches the flagellum bears a swelling called paraflagellar body (photoreceptor).
• The posterior end is pointed. The anterior end of the cell is blunt and bears an eccentric cytostome (mouth).
• At one end of the reservoir, the cytoplasm contains an orange red stigma (eye spot). Pyrenoids (proteinaceous bodies) may be present in the chloroplasts. The endoplasm contains several paramylum bodies.

Cleavage is a series of rapid mitotic divisions of the zygote, characterised by absence of growth in daughter cells, which converts a single celled zygote into a multicellular structure called blastocyst. It starts in the Fallopian tube and is holoblastic. Interphase in cleavage division is short and don not involve growth so that the resulting blastomeres become smaller in size as their number increases. During cleavage, at 8-16 celled stage, a solid ball of cells called morula (as it look like mulberry) is formed.
