Which one of the following rivers takes a 'U' turn at Nurricha Barwa and enters India ?

The Brahmaputra river, known as the Yarlung Tsangpo in Tibet, flows eastward parallel to the Himalayas for approximately 1,200 km [4]. Upon reaching the eastern anchor of the Great Himalayan Range at Namcha Barwa (7,757 m), the river executes a dramatic 'U' turn [2]. It pierces the Greater Himalayas through a deep gorge, often referred to as the Dihang-Gorge, and enters India in Arunachal Pradesh [3]. In this region, it is initially called the Siang or Dihang before being joined by tributaries like the Dibang and Lohit to form the Brahmaputra in the Assam valley [2]. The question contains a typographical error ('Nurricha' for Namcha and 'Brahnoputra' for Brahmaputra), but the geographical description of the 'U' turn at the 7,757 m peak uniquely identifies the Brahmaputra river system [4].
