What effect can the onset of monsoon have on temperature?

Correct answer: Relief from heat can occur

The direct answer is Option C: relief from heat can occur. Before the monsoon, many parts of India experience strong summer heat. When monsoon winds arrive, they often bring clouds and rain. Rain uses heat for evaporation, clouds reduce some incoming solar heating, and moist moving air can make conditions feel less intensely hot. Therefore, the onset of the monsoon can bring relief, although the exact temperature change differs by place and day. Option A is wrong because temperature does not always become exactly double; that is not a climatic rule. Option B is wrong because cloud, rain, wind, and humidity can change temperature and how heat is felt. Option C is correct because monsoon rainfall commonly reduces the intense summer heat. Option D is wrong because monsoon does not start snowfall everywhere; snowfall is limited mainly to high cold areas. Exam cue: monsoon arrival generally means rain and relief from pre-monsoon heat, not an identical change everywhere.
