Multilingualism in India intends teachers to understand :

India is a linguistically diverse country, and mainstream teacher-education theory (as in NCF 2005 and NCFTE 2009) treats this multilingualism as a resource rather than a problem: a teacher's role in a multilingual classroom is to make sure learners can communicate across their different mother tongues, and that this diversity strengthens, rather than fractures, the social fabric of the classroom.

Applied to this item, that is exactly what is being tested: multilingualism in India intends teachers to understand that education must ensure communication happens across language differences and that social cohesion is maintained despite them — this is the idea captured by 'communication happens, and social cohesion is maintained'.

Each of the other statements reverses this pluralistic view:

• Clubbing minority languages with dominant ones is an assimilationist move that erases linguistic diversity rather than valuing it — the opposite of what multilingual pedagogy recommends.

• Framing a single, uniform language policy for a diverse society ignores that India's linguistic plurality is precisely why approaches like the three-language formula exist, instead of one uniform language policy.

• Claiming that language, identity and culture are separate entities denies the well-established link between a learner's mother tongue and their sense of identity and culture — a link multilingual pedagogy is built around, not against.

So the statement that captures what multilingualism intends teachers to understand is the one about ensuring communication and social cohesion.
