The river mentioned in the question takes a U-turn after reaching Namcha Barwa and enters India through a gorge in Arunachal Pradesh. Let's explore the identity of this river.

Identification of the River

The correct answer to the question is option 'B' - Brahmaputra.

Explanation

The Brahmaputra River is one of the major rivers of Asia, flowing through Tibet, India, and Bangladesh. It originates from the Angsi Glacier in the Himalayas and is known as the Yarlung Tsangpo in Tibet. The river takes a U-turn at Namcha Barwa and enters India through a gorge known as the Namcha Barwa Canyon.

The Namcha Barwa Canyon is a magnificent natural wonder, with towering cliffs and steep gorges. It is one of the deepest and most inaccessible gorges in the world. The river cuts through the eastern Himalayas, forming the boundary between Tibet and Arunachal Pradesh.

After entering India, the Brahmaputra River flows through Arunachal Pradesh, where it is known as the Siang River. It then merges with the Dibang and Lohit rivers to form the mighty Brahmaputra. The river continues its journey through Assam and eventually enters Bangladesh, where it merges with the Ganges River to form the world's largest delta - the Sundarbans.

The Brahmaputra River is of great importance to the region. It supports a diverse ecosystem, providing water, food, and livelihoods to millions of people. The river is also a major transportation route, facilitating trade and commerce.

In conclusion, the river that takes a U-turn at Namcha Barwa and enters India through a gorge in Arunachal Pradesh is the Brahmaputra River. It is a significant river in Asia, playing a vital role in the lives of people in Tibet, India, and Bangladesh.
