The correct answer is: B) Bhopal.
The reorganization of states in 1956 led to the creation of Madhya Pradesh with Bhopal as its capital. Bhopal is the largest city in the state and is located in the central part of the country. It is a major industrial and commercial center and is also home to a number of educational institutions.
The other options are incorrect because they are not the capital of Madhya Pradesh. Jabalpur is a city in the central part of the state and is the headquarters of Jabalpur district. Gwalior is a city in the north-central part of the state and is the headquarters of Gwalior district. Indore is a city in the west-central part of the state and is the headquarters of Indore district.
