Correct Answer: Dihang gorge

Solution : The correct answer is Dihang Gorge .

The Himalayas' easternmost border is marked by the Namcha Barwa mountain and Brahmaputra River. The Himalayas begin to spread along India's eastern border beyond the Dihang Gorge before bending sharply to the south. Beyond the Dihang Gorge, the Himalayas curve sharply to the south and extend outward to form the eastern border of the nation. The Eastern Hills, or Purvanchal Hills, are their official name.
