Which option correctly shows the sequential position from mountains to plains in India's physical structure?

Correct answer: Northern Plains south of the Himalayas

The direct answer is A: Northern Plains south of the Himalayas. India’s broad north-to-south arrangement begins with the Himalayan Mountains in the north, followed immediately to their south by the Northern Plains. Rivers descending from the Himalayas deposit alluvium and form these level plains. Option A is correct because it gives the correct sequential relationship. Option B reverses the order; the Himalayas are north of the Northern Plains, not south of them. Option C is geographically impossible as a mountain-to-plain sequence: the Himalayas are not south of Lakshadweep, which is an island group far to the south-west. Option D does not describe the mountain-to-plain arrangement and also places unrelated regions together. Exam cue: from north to south, remember Himalayas, Northern Plains, then Peninsular Plateau.
