Answer
Both A and R are true and R is not the correct explanation of A.
Explanation — The Himalayas and Alps are indeed very high and have sharp peaks and steep slopes because they are young fold mountains and have not faced much erosion. On the other hand, old fold mountains have been worn down by denudation over millions of years. However, the reason given talks about old fold mountains and does not explain why the Himalayas and Alps are high and steep. Hence, R is not the correct explanation of A.
