Solution : The correct option is Bihar ( including the newly created Jhakhand )

Jharkhand, in eastern India, is known for possessing some of the country's greatest coal deposits. The state is rich in mineral resources, with coal accounting for a large portion of its natural wealth. Jharkhand's coal deposits are predominantly concentrated in the Damodar Valley area, which is known as the "Coal Capital of India". The Damodar Valley coalfields span many districts in Jharkhand, including Dhanbad, Bokaro, and Giridih. For decades, these coalfields have been critical to India's industrial and energy sectors. Coal from these deposits is utilised to fuel thermal power plants, businesses, and homes around the country.
