Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R) . Assertion (A) : Time period of a simple pendulum is longer at the top of a mountain than that at the base of the mountain. Reason (R) : Time period of a simple pendulum decreases with increasing value of acceleration due to gravity and vice-versa. In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both (A) and (R) are true but (R) is not the correct explanation of (A) .
2. Both (A) and (R) are true and (R) is the correct explanation of (A) .
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.

Correct answer: Both (A) and (R) are true and (R) is the correct explanation of (A) .
