Which of the following statements about power generation in Bihar is correct?

The correct answer is C, most of the state's generation is coal based. Bihar lies close to the coalfields of Jharkhand and West Bengal, and its large stations at Kahalgaon, Barh, Nabinagar, Barauni and Muzaffarpur all burn coal. The reorganisation of 2000 left the hill rivers, the coal bearing plateau and the older stations in Jharkhand, so the state rebuilt its capacity around new thermal projects on the Ganga and in the south.

Option A is wrong because Bihar has no atomic power station at all. Option B is wrong because the plain offers almost no fall, so hydel capacity is limited to small units such as Valmiki Nagar on the Gandak and Kataiya on the Kosi system. Option D is wrong because the state both generates a large quantity of power itself and draws a share from central sector stations. Solar parks and floating solar are growing but are still a small part of the mix.
