A. Saramati
B. Shillong
C. Namcha Barwa
D. Karbi

Answer 1

Hint:It is an isolated part of southeastern Tibet rarely visited by outsiders. It stands inside the Great Bend of the Yarlung Tsangpo River as the river enters its notable gorge across the Himalaya, emerging as the Siang and becoming the Brahmaputra.

Complete answer:
Option A. Saramati
At the mountainous border of the state of Nagaland, India, and the Sagaing Region, Burma, Saramati is a peak rising above the surrounding peaks. One of Southeast Asia's ultra-prominent peaks is Saramati.
There is no Brahmaputra flowing through Nagaland. Hence, this option is incorrect.

Option B. Shillong
 Shillong is a hill station situated between the Brahmaputra and Surma valleys in the northeastern part of India and the capital of Meghalaya. Therefore, Brahmaputra does not flow through Nagaland. Hence, this option is incorrect.

Option C. Namcha Barwa
In the Tibetian Himalaya, Namcha Barwa is a mountain peak. On reaching the Namcha Barwa, the Tsangpo -Brahmaputra River takes a U turn and enters India through a gorge in Arunachal Pradesh. Hence, this option is correct.

Option D. Karbi
Karbi Anglong Plateau, or Mikir Hills, in the Assam district of Karbi Anglong. Karbi Plateau, which is the easternmost portion of the projection towards the north-east. It is not a mountain peak.
 Namcha Barwa is the mountain peak located where a hairpin curve from the west - east trend to the north - south trend brings the Tsangpo - Brahmaputra River.

Therefore, from the above explanation, we can conclude that Option(C).

Note:1. The conventional description of the Himalayas extending to the Brahmaputra from the Indus River would make it the eastern anchor of the entire mountain range. It is the highest point in its own segment, as well as the easternmost peak over 7,600 meters on Earth.
2. Namcha Barwa is scarcely visited by outsiders in a remote region of southeastern Tibet. It stands within the Yarlung Tsangpo River's Great Bend. Emerging as the Siang and becoming the Brahmaputra as it reaches its notable gorge across the Himalaya.
