Which of the following is NOT a part of the Purvanchal or Eastern Hills?
- A.Patkai Bum
- B.Naga Hills
- C.Mizo Hills
- D.Aravalli Hills
Correct answer
Explanation
The correct answer is D, Aravalli Hills. The Purvanchal or Eastern Hills are the southward continuation of the Himalayas beyond the eastern bend of the Brahmaputra, and they are made up of the Patkai Bum, the Naga Hills, the Manipur Hills and the Mizo or Lushai Hills. They are lower than the main Himalayan ranges and are composed largely of soft sandstone. The Aravalli, by contrast, is one of the oldest fold mountain systems in the world, a residual range running north-east from Gujarat through Rajasthan to Delhi, with Guru Shikhar on Mount Abu as its highest point. Option A is wrong because the Patkai Bum lies along the Arunachal Pradesh border with Myanmar. Option B is wrong because the Naga Hills are in Nagaland, and Option C is wrong because the Mizo Hills are in Mizoram.

- A.Khadar
- B.Bhabar
