Which statement is most balanced in the study of mountains and plateaus in India?

Correct answer: Himalayas are young mountains while Deccan Plateau is an ancient rocky plateau region

Option A is the balanced and geographically accurate statement. The Himalayas are young fold mountains formed through the continuing convergence and collision of the Indian and Eurasian plates. Their relief is comparatively young, high, and tectonically active. In contrast, the Deccan Plateau is an ancient, stable block of the Peninsular Plateau, built largely from old crystalline rocks and extensive basaltic lava flows in parts of the Deccan Trap region. Options B and C wrongly treat the Himalayas and Deccan as parts of one landform system, while option D reverses the obvious height relationship. Therefore A correctly compares two different major physiographic divisions.
