It descends through the mountainous region and surges through Arunachal Pradesh in India for 200 kilometres before entering the plains of Assam where it is known as the Lohit River. Hence, 2 is correct.
• Subansiri rises in the mountains of Tibet. The total length of the Subansiri is about 442 km, out of which 192 km lies in Arunachal Pradesh and 190 km in Assam and the rest part falls in Tibet. Hence, 3 is correct.
