Read the following statements and choose the correct option :
Assertion (A) : Reading and writing skills help in critical thinking at the primary level.
Reason (R) : Critical thinking is a sub-skill of reading and writing.

The correct option is (A) is true, but (R) is false.

Explanation:

Assertion (A): Reading and writing skills help in critical thinking at the primary level.
This statement is true. Developing foundational reading and writing skills enables learners at the primary level to analyze information, make connections, ask questions, and express their thoughts, which fosters critical thinking.

Reason (R): Critical thinking is a sub-skill of reading and writing.
This statement is false. Critical thinking is a higher-order cognitive skill or overarching mental process, not merely a sub-skill of reading and writing. Rather, reading and writing serve as tools and mediums through which critical thinking is practiced and demonstrated.

Therefore, Assertion (A) is correct, while Reason (R) is incorrect.
