Multiple choice

Directions: The followings item consist of two statements, one labeled as the 'Assertion (A)' and the other as 'Reason (R)'. You are to examine these two statements carefully and select the answer to these items using the codes given below.

Assertion (A) : Tropical cyclones do not develop very close to the equator. Reason(R) : A weak circular effect retards the development of circular air motion.

  1. Both A and R are individually true and R is the correct explanation of A

  2. Both A and R are individually true but R is NOT the correct explanation of A

  3. A is true but R is false

  4. A is false but R is true

C Correct answer
Explanation

The Assertion is correct - tropical cyclones typically do not develop within 3-5 degrees of the equator because the Coriolis force (essential for cyclonic rotation) is too weak near the equator. However, the Reason is false - the problem is not a 'weak circular effect' but rather the insufficient Coriolis force, which is caused by Earth's rotation. The correct reason would mention Coriolis force, not circular effect.
