Which of the following folk music of Chhattisgarh is based on the epic Mahabharata?

The correct answer is Pandavani.

Explanation:

Pandavani is a traditional folk singing/performing art style native to the state of Chhattisgarh (as well as neighboring areas of Madhya Pradesh, Odisha, and Andhra Pradesh). It depicts story recitations and musical narrations of episodes from the ancient Indian epic, the Mahabharata, with particular emphasis on the adventures of the Pandava brothers (especially Bhima).

Let us look at the other options for clarity:

• Paani Haari: A traditional folk dance form from Rajasthan, associated with women carrying water pots.
• Ghumar: A traditional folk dance of Rajasthan, performed by women on special occasions.
• Maand: A famous folk music style originating from the Marwar region of Rajasthan.

Therefore, Pandavani is the folk music of Chhattisgarh based on the Mahabharata.
