Correct option is A

The correct answer is Retreating of South-west Monsoon
The Tamil Nadu Coast receives rainfall during the winter season mainly due to the Retreating of South-west Monsoon. During this time, the monsoon winds reverse their direction, blowing from the northeast towards the southwest. These northeast winds pick up moisture from the Bay of Bengal and bring significant rainfall to Tamil Nadu’s coastal areas. This seasonal phenomenon is also termed as the Northeast Monsoon or Retreating Monsoon. It usually occurs from October to December, making it critical for Tamil Nadu's agriculture and water needs.
Information Booster:
· The Retreating of South-west Monsoon is responsible for winter rainfall along the Tamil Nadu coast.
· During this retreat, winds shift direction, becoming northeast winds that carry moisture from the Bay of Bengal.
· This period is vital for replenishing water sources and sustaining rice cultivation and other agricultural activities in Tamil Nadu.
· The Northeast Monsoon is an essential climatic feature for Tamil Nadu, as it receives much of its annual rainfall during this season.
