Which of the following is the easternmost range of the Himalayas?

The correct option is Purvanchal Range.

Step-by-step Explanation:

1. The Himalayas stretch across the northern border of India from west to east. Beyond the Dihang gorge, the Himalayas bend sharply to the south and spread along the eastern boundary of India.

2. These Eastern hills are collectively known as the Purvanchal Range (or Eastern Highlands). They comprise ranges such as the Patkai Hills, Naga Hills, Manipur Hills, and Mizo Hills, forming the easternmost extremity of the Himalayan mountain system.

3. Let us look at the geographic position of the other given options:

• Zanskar: Located in the Trans-Himalayan region (North/Northwest of India).

• Dhauladhar: Part of the Lesser Himalayas, situated primarily in Himachal Pradesh (Northern India).

• Pir Panjal: The largest range of the Lesser Himalayas, located in Jammu and Kashmir and Himachal Pradesh (Western/Northwestern Himalayas).

Therefore, the Purvanchal Range is the easternmost range of the Himalayas.
