One of the tribes which celebrates ‘Sarhul’ festival is

Santhal
Munda
Bhil
Tharu

The correct answer is (a) Santhal.

Sarhul is a major festival of the Santhal tribe of Jharkhand, India. It is a harvest festival that is celebrated in the month of Chaitra (March–April). The festival marks the beginning of the new agricultural year and is a time for thanksgiving to the gods for a good harvest.

The festival is celebrated with great pomp and show. People wear their best clothes and dance and sing to the beat of drums. The main attraction of the festival is the worship of the Sarhul tree, which is considered to be sacred by the Santhals. The tree is decorated with flowers and leaves and offerings are made to it.

The festival is also a time for social gatherings and feasting. People visit each other’s houses and exchange gifts. The festival is a time of joy and celebration for the Santhals and it is a time to renew their bonds with their community and their culture.

The other options are incorrect because they are not tribes that celebrate the Sarhul festival. The Bhil tribe celebrates the Bhaubeej festival, the Munda tribe celebrates the Karma festival, and the Tharu tribe celebrates the Maghi festival.
