The International Day for Disarmament and Non-Proliferation Awareness, established by a UNGA resolution on December 7, 2022, was first observed on March 5, 2023. This day aims to raise public awareness, especially among youth, regarding the significance of disarmament efforts globally.

Inclusive education is an approach, seeks to address the learning needs of all children, youth, and adults with a specific focus on those who are vulnerable to marginalization and exclusion.

• It implies all learners, young people - with or without disabilities being able to learn together through access to common pre-school provisions, schools, and community educational settings with an appropriate network of support services.

Key Points

• An inclusive classroom promotes learning of all children, with special abilities, with various social backgrounds, and with diverse learning needs.
• In the inclusive classroom, each student gets access to knowledge, skills, and information, which improve available choices to all children and we do not necessarily limit ourselves to the knowledge domain, but rather include the affective domain, and the attitudinal domain as well.
• Every child gets the opportunity for quality and optimal learning and for enjoying learning together and actively participating in learning activities. The activities are more-cooperative and collaborative so that each child can participate effectively.
• In an inclusive classroom, there will be less stress on competition, grades, and covering the course as the child will be given importance so that they can learn effectively.

Thus, it is concluded that more effort by teachers to "cover" courses is least important in an inclusive classroom.

Context is the spoken or written form of material that can be used for teaching Grammar.

Programmed instruction method is most suitable to teach heterogeneous group of students for self placed learning. Programmed instruction is a method of presenting new subject matters to students in a graded sequence of controlled steps.

'Education-of-all-in-schools-for-all' is a tagline for Inclusive education.
Inclusive education is a platform that promotes and believes that every child should get equal opportunity irrespective of caste, creed, colour, religion and whether a child is a normal or special case. 
It mainly focuses on providing education to special children, along with children with non-special needs. It welcomes special-needs children to promote equality.
Hence, the correct answer is, 'Inclusive education.

Number of electrons in bonding orbital = 4 and in anti-bonding orbitai = 0

Non metallic oxides are acidic.

(i) → (r,s), (ii) → (p,q,t), (iii) → (p,q,t), (iv) → (r,s)

Greater the surface area, greater will be the area available for adsorption.

Pure phoshine is not inflammable but due to contamination of P₂H₄ and P₄ vapours, it becomes inflammabl.

The potential energy of an electron in the first Bohr’s orbit in the H-atom is

This energy is defined as an atomic unit of energy called HARTREE.

The correct answer is option A
In Tyndall effect the colloidally suspended particles trace out the path of the strong beam of light because of scattering of light by the colloidal particles.
 

On addition of H₂/Pd/CaCO₃
we get H-CH=C-CH₂-CH₂-CH₃ 
H-CH=C-CH₂-CH₂-CH₃ + NBS/CCl₄   →   H-CH=C-CHCl-CH₂-CH₃  (NBS adds Br to carbon at next alternate to double bond)
H-CH=C-CHCl-CH₂-CH₃ + KOH/EtOH  →  H₂C=C-CH=CH-CH₃
(by E₂ elimination)

1 and 2 are non-superimposable mirror images of each other. So, according to the options given, 1 and 2 are enantiomers of each other.

Xenon reacts with fluorine at 873 K and 7 bar to form XeF4. In this reaction, the ratio of Xenon and fluorine required is 1:5

NaCl Solution : pH is the, pH   of water.

pH at 25°C <7

All isomeric esters are metamers.

Mn²⁺/ Mn have - 1.18SRPvalue.

Smaller the IE of Mg, easier the formation of Mg²⁺.
Greater the EA of O, easier the formation of O2^-.

In S_N1 reaction, some of the substrate, even after ionisation, remains associated as an intimate ion pair preventing nucleophilic attacks from front side and gives inverted product.

Due to partial reaction of nucleophile with intimate ion pair, net inversion of configuration is observed although predominant reaction occurs at planar carbocation giving racemic products.

LiAIH₄ reduces both carbonyls and carboxylic groups but does not reduce olefinic bond.

Fluorine is most electronegative element therefore can only gain electrons. Thus it only shows negative oxidation state.

Explanation of Chelating Ligand
A chelating ligand is a molecule that forms multiple bonds with a single metal ion. In other words, it can bind to a metal ion at more than one point, creating a ring-like structure. This process is known as chelation. Chelating ligands have two or more donor atoms, which allow them to form multiple bonds with a single metal ion. These ligands are used in various fields such as medicine, chemistry, and environmental science due to their ability to sequester metal ions.

Examination of Options
A: Cl^- Chloride ion (Cl-) is a monodentate ligand, meaning it can bind to a metal ion at only one point. Therefore, it is not a chelating ligand.
B: DMG DMG, or Dimethylglyoxime, is a type of ligand that can bind to a metal ion at two points, forming a five-membered ring. Thus, DMG is a chelating ligand.

C: H₂O Water (H₂O) is a monodentate ligand, meaning it can bind to a metal ion at only one point. Therefore, it is not a chelating ligand.
D: OH^- Hydroxide ion (OH^-) is a monodentate ligand, meaning it can bind to a metal ion at only one point. Therefore, it is not a chelating ligand.

Conclusion
Therefore, out of the given options, only DMG (Dimethylglyoxime) is a chelating ligand. Hence, the correct answer is B: DMG.
