The correct answer is January.

Pongal is a four-day harvest festival celebrated in the Indian state of Tamil Nadu. It is one of the most important festivals in the state and is celebrated with great pomp and show. The first day of Pongal is called Bhogi, which is a day of cleaning and getting rid of old things. The second day is called Surya Pongal, which is a day of worshipping the sun god. The third day is called Mattu Pongal, which is a day of worshipping cattle. The fourth and final day is called Kaanum Pongal, which is a day of feasting and merrymaking.

Pongal is a time for family and friends to come together and celebrate the harvest. It is also a time to give thanks to the sun god for his blessings. The festival is celebrated with a variety of activities, including music, dance, and feasting.

Pongal is a time of great joy and celebration. It is a time to reflect on the past year and to look forward to the year ahead. It is a time to be grateful for all that we have and to celebrate the bounty of the harvest.

The other options are incorrect because Pongal is not celebrated in those months.
