Explanation: The Himalayas are the youngest mountain range in the world.

They were formed about 50 million years ago due to the collision of the Indian Plate and the Eurasian Plate.

The Himalayas are still growing and rising due to ongoing tectonic activity.

This range includes the highest peaks in the world, such as Mount Everest (8,848.86 m).


Other Options Explained:

(B) Alps – Formed about 30-40 million years ago, older than the Himalayas.

(C) Andes – The longest continental mountain range, formed around 65 million years ago.

(D) Rockies – Formed about 70-80 million years ago, older than the Himalayas.


Thus, the correct answer is (A) Himalayas.
