The correct answer is B. Latehar.
A municipal corporation is a local government body that is responsible for the administration of a city or town. It is a statutory body that is created by an act of the legislature. The municipal corporation has its own elected body, called the municipal council, which is responsible for the day-to-day administration of the city. The municipal corporation also has a chief executive officer, called the municipal commissioner, who is appointed by the state government.
Dhanbad, Deoghar, and Ranchi are all municipal corporations. Latehar is not a municipal corporation. It is a district in the state of Jharkhand.
