Dr. Rajendra Prasad was the first male President of India. He served as the President from 1950 to 1962.

Total females = 100% - 52% = 48%
So the answer = (100 – 60)% of 52% + (100 – 70)% of 48% = 35.20%
Hence, Option B is correct.

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.

Parents should show trust in the teacher and discuss the problem with the teacher. In case, he does not feel satisfied, can he take some other action for the same. The parents must try to understand the teacher's point of view, as well as should be able to make the teacher understand their own point of view. Thus, they both can come to a common conclusion.

When the children do new things that they did differently from what they did before, creativity, creativity is a skill that helps children to enhance their skills of thoughts, ideas, feeling, etc. It's just that they make new things on their own. Creativity is something kids like when they play or make connections for different reasons.
Hence, the correct answer is "Play".

Fluency, elaboration, originality and flexibility are associated with divergent thinking. Divergent thinking is creating multiple ideas, unique possible solutions, or ideas of a problem in a short period. Fluency, elaboration, originality, and flexibility are the dimensions of Divergent thinking and are associated with giftedness. Divergent thinking is important in the creative thinking process. Guilford (1986) considered creative thinking as involving divergent thinking, consisting of four elements: fluency, flexibility, originality, and elaboration. 
Thus, this is the correct answer. 

In the triarchic theory, three types of intelligence proposed by Robert Sternberg are: Analytical, Creative and Practical.

The parameters which must be considered while choosing the teaching methodologies include:
Capacity of the students: Choosing lecture method to teach 6th grade student will not help the teacher to attain his goal of teaching because the child cannot understand the concept just by mere lecturing. Hence to such grade, demonstration method of teaching must be chosen.
Content: Based upon the content, the teacher should decide the methodology.
Nature of the subject: Before deciding the method of teaching, the instructor must keep in mind the nature of the subject because the methods of teaching of science-based subjects is different from those of humanities.

A teacher having a democratic nature permits students to sit all over the class in which some sit together and discuss or do group reading. Some sit quietly and read themselves. If a parent does not like this behaviour of a teacher then they should show trust in the teacher and discuss the problem with the teacher. Maybe the teacher is doing this with positive hidden motives.
Hence, the correct answer is, 'Parents should show trust in the teacher and discuss the problem with the teacher.'

The New Education Policy lays particular emphasis on the development of the creative potential of each individual. It is based on the principle that education must develop not only cognitive capacities - both the ‘foundational capacities ’of literacy and numeracy and ‘higher-order’ cognitive capacities, such as critical thinking and problem solving – but also social, ethical, and emotional capacities and dispositions. 

Key Points Following are the proposals made by National Education Policy 2020 (NEP):-

•  a variety of methods and strategies such as group work and role plays be used for assessment. 
•  apart from assessment by the teacher, other ways such as self-assessment and peer-assessment should be encouraged.
•  report card of the student should include progress in the cognitive, affective, and psychomotor domains. 
• focus on regular formative assessment for learning rather than the summative assessment that encourages today’s ‘coaching culture.

​Thus, it is concluded that NEP 2020 proposes shift from formative to summative assessment regarding proposals made by National Education Policy 2020 (NEP) is not correct.

Every child has an interest in listening to stories. So, if a teacher tells interesting stories to students while teaching the subject, it develops an interest in students and they concentrate properly in class.

A school-based assessment is done within the school by the teachers. It makes the learning relevant and can motivate students through the diagnosis of learning gaps. It helps to know the children's strengths and weaknesses. So, the school-based assessment helps all students learn more through diagnosis.
Hence, the correct answer is, 'Helps all students learn more through diagnosis.'

Progressive education advocates that young learners should be given the freedom to learn according to their preferences and likes

I.E. in a group decreases and reactivity increases.

In 1913, Henry Moseley showed that the atomic number of an element is a more fundamental property than its atomic mass.

Since, F^- ion is a weak ligand hence, pairing of electrons does not occur and outer orbital complex is formed in [CoF₆]^3-.

Bryophytes are called as amphibians of plant kingdom as bryophytes can grow in both land andwater. Water is essential for completion of life cycle. So, they are called amphibians of plant kingdom.

(Total molecules utilized are 18 and produced are 13. Therefore total is 31) 

In most of the higher plants, the growing apical bud inhibits the growth ofthe lateral (axillary) buds, a phenomenon called apical dominance.

Artificial classification is based on morphological structures of the plant i.e. artificial classification focuses on external structure of the plants than their internal structure.

During noncyclic electron flow the electron hole in P-680 is filled by electrons obtained by photolysis of water. As a result, there is an evolution of oxygen and the electron move through Mn-protein bound to PS II. In this transport Mn⁺⁺ is oxidised to Mn⁺⁺⁺ and then reduced to Mn⁺⁺ in a cyclic manner. The manganese thus transfers electrons from water to photosystem II and thus plays an important role in electron transport in the process of photosynthesis.

The word “karyo” means nucleus and “gamy” means fusion. Therefore the word “karyogamy” refers to the fusion of nuclei. In the sexual cycle of fungus to form spores, plasmogamy is followed by karyogamy and then by meiosis.

• Lanolin or wool fat is a wax secreted by the sebaceous glands of wool-bearing animals.
• Lanolin used by humans comes from domestic sheep breeds that are raised specifically for their wool.

Testosterone hormone help in release of sperm from testis. This hormone is released by leydig cells present in between seminiferous tubules of testis.

• Methanogens are a group of obligate anaerobic ancient and primitive bacteria.
• Methanogens are present in the gut of several ruminant animals such as cows and buffaloes and they are responsible for the production of methane (biogas) from the dung of these animals.
• They are involved in methanogenesis and produce methane gas.

Hence, the correct option is B
