Correct option is B
The Coromandel Coast receives heavy rainfall in October and November, primarily due to the northeast monsoon. Unlike the more widespread southwest monsoon that affects much of India from June to September, the northeast monsoon brings significant precipitation to the southeastern coast.
This period, often referred to as the retreating monsoon season, is characterized by the reversal of winds that pick up moisture from the Bay of Bengal and deposit it over the Coromandel Coast.
The rains are crucial for the region's agriculture, particularly for water-intensive crops like rice.
However, the intensity of the rainfall can sometimes lead to flooding and associated challenges for the local population and economy.
