Explanations:The people of Assam celebrate Bihu, which is a traditional festival marking the different phases of the agricultural year. Bihu is a significant cultural event that reflects the agricultural and social life of the Assamese people. There are three types of Bihu celebrated in Assam: Rongali Bihu, Kongali Bihu, and Bhogali Bihu.
Rongali Bihu, also known as Bohag Bihu, is celebrated in mid-April and marks the beginning of the Assamese New Year. It is a time of joy and celebration, with people engaging in traditional dances, songs, and feasts. The festival is associated with the spring season and the beginning of the sowing period.
Kongali Bihu, also known as Kati Bihu, is celebrated in mid-October and is a more subdued festival compared to Rongali Bihu. It is a time when the crops are growing, and the fields are green. People light lamps in the fields and around their homes to ward off evil spirits and pray for a good harvest.
Bhogali Bihu, also known as Magh Bihu, is celebrated in mid-January and marks the end of the harvesting period. It is a time of feasting and community gatherings, with people preparing traditional dishes and sharing them with their neighbors. The festival is associated with the winter season and the end of the agricultural cycle.
While other festivals like Pongal, Durga Puja, and Rath Yatra are celebrated in different parts of India, they are not specific to Assam. Pongal is a harvest festival celebrated in Tamil Nadu, Durga Puja is a major festival celebrated in West Bengal and other parts of India, and Rath Yatra is a major festival celebrated in Odisha and other parts of India. Therefore, Bihu is the correct answer as it is a traditional festival celebrated in Assam.
