Given below are two statements, one is labelled as Assertion (A and the other is labelled as Reason (R).
Assertion (A): In extensive reading, the teachers play the main role
Reason (R): The aim of extensive reading is to enrich learners’ knowledge
In light of the above statements, choose the most appropriate answer from the options given below:

The correct option is: (A) is not correct but (R) is correct.

Let us analyze both statements step-by-step to understand why this option is correct:

1. Analysis of Assertion (A): "In extensive reading, the teachers play the main role"
Extensive reading involves reading longer texts or books for general understanding and pleasure, usually outside the classroom at the learner's own pace. In this approach, the learner is the active participant and plays the central or main role. The teacher's role is passive and facilitative—mainly limited to guiding, encouraging, and providing appropriate reading materials. Therefore, the assertion that the teacher plays the main role is incorrect (not correct).

2. Analysis of Reason (R): "The aim of extensive reading is to enrich learners’ knowledge"
The primary objective of extensive reading is to foster a habit of reading, develop a love for literature, improve general language proficiency, and ultimately enrich the learners' overall knowledge and vocabulary. Thus, this statement is factually correct.

Since Assertion (A) is incorrect and Reason (R) is correct, the most appropriate choice is indeed that (A) is not correct but (R) is correct.
