The river Brahmaputra enters India from which of the following states?

The correct answer is Option 1, i.e Arunachal Pradesh . Key Points The river Brahmaputra enters India from the state of Arunachal Pradesh. The Brahmaputra rises in Tibet east of Mansarowar Lake very close to the sources of the Indus and the Satluj. It is slightly longer than the Indus , and most of its course lies outside India. It flows eastwards parallel to the Himalayas. On reaching the Namcha Barwa (7757 m) , it takes a ‘U’ turn and enters India in Arunachal Pradesh through a gorge. Here, it is called the Dihang and it is joined by the Dibang , the Lohit , and many other tributaries to form the Brahmaputra in Assam.
