Solution
Both A and R are true, but R is not the correct reason for A.
Explanation:
Convectional rainfall is indeed common in the Equatorial region (Assertion A is true) because intense heating of the surface causes warm, moist air to rise and form clouds, leading to rainfall. The Reason R says convectional rainfall does not last long, which is also true because convectional rains are usually short but intense. However, the short duration (R) is not the reason why convectional rainfall is common in the Equatorial region (A). The occurrence in the Equatorial region is mainly due to the intense surface heating and vertical sun rays, not the duration of rainfall.
