Balaghat Range should be associated with which wider physical region?

Correct answer: Deccan Plateau region

The governing concept is the regional classification of hill ranges within the Peninsular Plateau. The Balaghat Range is associated with the Deccan Plateau and extends through parts of the Maharashtra–Karnataka upland region. It is an old peninsular highland rather than a young Himalayan or alluvial landform. Therefore option A is correct. The Ganga Plain is a level depositional plain formed largely by river sediments, the Sikkim Himalaya belongs to the young fold mountains of the north, and the Meghalaya Plateau is an isolated north-eastern plateau. These regions differ in origin, location and relief, so they cannot provide the appropriate wider association for the Balaghat Range.
