The correct answer is option 3: Both 1 and 2.

Statement 1 states that rainfall in the doldrums is of convectional nature. Convectional rainfall occurs when the ground is heated by the sun, causing the air near the ground to heat up and rise. As the warm air rises, it cools and condenses, forming clouds and eventually leading to rainfall. The doldrums are areas near the equator where the trade winds converge, resulting in warm, moist air. This warm, moist air rises, cools, and condenses in a convectional process, resulting in rainfall. Therefore, statement 1 is correct.

Statement 2 states that convectional rainfall is highly localized and is associated with minimum cloudiness. Convectional rainfall is indeed highly localized, meaning it occurs in specific areas rather than being spread out over a large region. This is because convectional rainfall relies on the localized heating of the ground to initiate the convection process. However, it is important to note that convectional rainfall is typically associated with the formation of cumulus clouds, which are fluffy and can be quite large. These clouds are formed due to the rising and condensing of warm air. Therefore, statement 2
