Why can pre-monsoon showers be useful in some regions?

Correct answer: They can provide initial soil moisture and relief from heat

The direct answer is A: pre-monsoon showers can provide initial soil moisture and relief from heat. These showers occur before the main southwest monsoon in some places. Rain wets the upper soil, lowers intense heat for a time and may help farmers prepare fields or support certain early crops. The reasoning is: hot pre-monsoon conditions may be followed by local storms; rain enters the soil; soil moisture and cooler conditions can help agricultural preparation. Option A says “can” and “in some regions,” so it correctly allows for regional differences. Option B is wrong because such showers do not occur only to destroy crops; their effects depend on amount and timing. Option C is physically absurd: rain does not dry the sea. Option D is unrelated because rainfall does not reduce the height of the Himalayas. Remember: pre-monsoon rain may be locally useful, but it is not the same as the full monsoon season.
