Why is the Aravalli remembered among India’s oldest mountain ranges?
Answer and explanation
Correct answer: It is a very old mountain range
The governing concept is the geological age and evolution of mountain systems. The Aravalli Range is regarded as one of India's oldest fold mountain systems, formed through ancient geological processes and subsequently worn down by prolonged erosion. Its present form is therefore much lower and more discontinuous than young, lofty ranges such as the Himalayas. Option C is correct because it states the defining reason for its importance in Indian geography. Option A reverses the fact: the Aravallis are not a very new range. Option B confuses a mountain range with an island, while option D describes neither their geology nor their general landscape. Their antiquity, not permanent snow cover, is the key idea.
