Exp) Option c is the correct answer.

The power to create new districts or alter or abolish existing districts rests with the State governments. This can either be done through an executive order or by passing a law in the State Assembly. Many States prefer the executive route by simply issuing a notification in the official gazette.

Centre has no role to play in the alteration of districts or creation of new ones. States are free to decide. Home Ministry comes into the picture when a State wants to change the name of a district or a railway station. The departments such as the Ministry of Earth Sciences, Intelligence Bureau, Department of Posts, Geographical Survey of India Sciences, and the Railway Ministry, provides their clearance to the proposal of state government. After examination of their replies, state government receives a no-objection certificate.
