Consider the following pairs:

Peak	Mountains
1. Namcha Barwa	Garhwal Himalaya
2. Nanda Devi	Kumaon Himalaya
3. Nokrek	Sikkim Himalaya

Which of the pairs given above is/are correctly matched ?

The correct option is 2 only.

Let us analyze each pair step-by-step to understand why only the second pair is correctly matched:

1. Namcha Barwa – Garhwal Himalaya (Incorrect):
Namcha Barwa is a prominent mountain peak located in the extreme eastern part of the Himalayas, near the Great Bend of the Yarlung Tsangpo (Brahmaputra) River in Tibet/Arunachal Pradesh region. On the other hand, the Garhwal Himalayas are situated in the western parts of the Himalayas, primarily in the state of Uttarakhand, India. Therefore, Namcha Barwa does not lie in the Garhwal Himalayas; it belongs to the Eastern (Assam) Himalayas.

2. Nanda Devi – Kumaon Himalaya (Correct):
Nanda Devi is the second-highest mountain peak in India and the highest located entirely within the country. It is situated in the state of Uttarakhand, which is part of the Kumaon (and Garhwal) division of the Himalayas. Thus, matching Nanda Devi with the Kumaon Himalayas is geographically correct.

3. Nokrek – Sikkim Himalaya (Incorrect):
Nokrek is the highest peak of the Garo Hills, located in the state of Meghalaya in northeast India (part of the Shillong Plateau/Meghalaya Plateau), rather than the Himalayan mountain range proper. The Sikkim Himalayas are located much further north, primarily in the state of Sikkim. Thus, matching Nokrek with the Sikkim Himalayas is incorrect.

Consequently, only pair 2 is correctly matched, making "2 only" the correct answer.
