Correct option is C
Assertion (A) is true as our brain is naturally adept at learning content that is related to real-world contexts, especially from an early age. This type of learning is engaging and relevant, making it easier for students to grasp and retain information. However, Reason (R) is false because emphasizing only abstract content and textbook learning in primary grades can be counterproductive. It overlooks the importance of contextual and experiential learning, which are crucial for young students. Therefore, while the assertion is true, the reason is not correct.
