NCF-2005 mainly recommended:

Correct response: Connecting knowledge to life outside the school — ज्ञान को विद्यालय के बाहर के परिवेश से सम्बद्ध करना. Why this is the main recommendation: NCF-2005 advocated making learning meaningful by linking classroom content to children’s everyday life, communities and experiences.

It emphasised child-centred, activity-based and experiential approaches rather than rote memorisation.

Other key aims included making learning enjoyable, reducing stress on students, and promoting understanding over memorisation.

Why the other choices are not the primary NCF-2005 recommendation: Reducing teacher–pupil ratio: desirable for improving classroom conditions, but not the central pedagogical focus of NCF-2005.

25% reservation for economically weaker sections: this specific provision was implemented later through the RTE Act, 2009; NCF-2005 discussed equity but did not prescribe this exact policy.

Development of school infrastructure: important as support for quality education, but infrastructure was not the main curricular and pedagogical emphasis of NCF-2005.

Key takeaway: NCF-2005 prioritised making learning child-centred, experiential and connected to real-life contexts; this focus on meaningful learning is why connecting knowledge to life outside school is the best summary of its main recommendation.
