  • Assertion (A) is correct. The statement accurately describes the Himalayas as geologically young and structurally fold mountains.
  • Reason (R) is correct as well. The description of the Himalayas as an unstable zone with youthful topography, high peaks, deep valleys, and fast-flowing rivers aligns with the geological characteristics of the region.
  • The Reason is the correct explanation of the Assertion because the youthfulness of the Himalayas and their structural fold nature contribute to their instability, leading to high peaks, deep valleys, and fast-flowing rivers.
  • Therefore, Option A is the correct answer.

Assertion (A): The Himalayas are considered geologically young and str...
Explanation:
The Himalayas are considered geologically young and structurally fold mountains because of the following reasons:

Formation:
- The Himalayas were formed as a result of the collision between the Indian Plate and the Eurasian Plate.
- This collision led to the upliftment of the Himalayan range, making them relatively young in geological terms.

Unstable Zone:
- The Himalayas form an unstable zone due to their youthful topography with high peaks, deep valleys, and fast-flowing rivers.
- The young age of the Himalayas contributes to their unstable nature as they are still undergoing geological processes like erosion, landslides, and earthquakes.
Therefore, both the Assertion and Reason are true, and the Reason is the correct explanation of the Assertion. The youthfulness of the Himalayas is directly related to their status as geologically young and structurally fold mountains, making them an unstable zone with dynamic geological processes.
