Correct Answer:
A. Monsoon
This question pertains to the climatic patterns of Pakistan. Pakistan receives its primary rainfall during the Monsoon season, which typically occurs from July to September. The monsoon is a seasonal reversal of winds, bringing moist air from the Arabian Sea and Bay of Bengal, resulting in heavy and widespread precipitation across much of the country, crucial for agriculture and water resources.
- While July to September falls within the broader Summer season, 'Monsoon' specifically describes the atmospheric phenomenon responsible for the rainfall.
- Winter in Pakistan (December-February) receives rainfall from western disturbances, which is generally lighter and less widespread than monsoon rains.
- Autumn (October-November) follows the monsoon, and rainfall significantly decreases during this period.
