Correct Answer: B
Detailed Solution
Rainfall along the coastal areas of Tamil Nadu at the beginning of winter is mainly caused by the North-East Monsoon. During October-November, the South-West Monsoon begins to retreat from India and the wind direction reverses. These north-easterly winds pick up moisture while passing over the Bay of Bengal and bring rainfall to the Tamil Nadu coast.
