Which option gives a correct group of mountains and plateaus from north, south, and north-east India?

Correct answer: Himalayas, Western Ghats, and Meghalaya Plateau

Option A provides a correct regional group of major mountain and plateau features. The Himalayas occupy the northern margin of India, the Western Ghats run along much of the western edge of the Peninsular Plateau in southern and west-central India, and the Meghalaya Plateau lies in the northeast. The question asks for landforms from three regions, not rivers, lakes, islands, deserts, or coastal features. Option B lists two rivers and a lagoon, option C combines a desert, a deltaic wetland, and a lake, and option D mainly lists islands or a coastal region rather than the required mountain-plateau group. Hence A is the only suitable answer.
