Step 1: Understanding the Concept: Assertion-Reasoning questions require verifying the truth of both statements individually, and then determining if the Reason directly explains *why* the Assertion is true.
Step 2: Detailed Explanation: The Assertion states that ECCE aims for holistic development so children realize their full potential. This statement is factually true according to educational frameworks.
The Reason states that educators must recognize individual strengths and cultural context to design inclusive activities. This statement is also factually true, as it represents a best practice in pedagogy.
However, the Reason does not explain *why* the objective is holistic development. Instead, the Reason describes the *method* or *approach* educators should take to achieve that objective.
Because it provides the 'how' rather than the 'why', it is not the definitive explanation of the Assertion's objective.
Step 3: Final Answer: Both statements are true independently, but R is not the correct explanation of A.
