The correct answer is Option 4: 1, 2 and 3.

All three rivers mentioned in the options - Dibang, Kameng, and Lohit - are tributaries of the Brahmaputra River, which is one of the major rivers of Asia and flows through India, China, and Bangladesh.

Here`s a detailed reasoning for each option:

Option 1: 1 only

This option is incorrect as it only considers Dibang as a tributary of the Brahmaputra, which is not accurate. Dibang River is indeed a tributary of Brahmaputra River and flows through Arunachal Pradesh in India. However, it is not the only tributary of Brahmaputra River.

Option 2: 2 and 3 only

This option is also incorrect as it only considers Kameng and Lohit as tributaries of the Brahmaputra, which is not accurate. Kameng River and Lohit River are both tributaries of the Brahmaputra River and flow through Arunachal Pradesh in India. However, it does not include Dibang River, which is also a tributary of the Brahmaputra River.

Option 3: 1 and 3 only

This option is incorrect as it only considers Dibang and Lohit as tributaries of the Brahmaputra, which is not accurate. Dibang River and Lohit River are both tributaries of the Brahmaputra River and flow through Arunachal Pradesh in India. However, it does not include Kameng River, which is also a tributary of the Brahmaputra River.

Option 4: 1, 2 and 3

This option is correct as it includes all three rivers - Dibang, Kameng, and Lohit - which are indeed tributaries of the Brahmaputra River. Dibang River, Kameng River, and Lohit River all flow through Arunachal Pradesh in India and eventually join the Brahmaputra River.

It`s important to note that Brahmaputra River is a transboundary river, flowing through China, India, and Bangladesh, and has several tributaries on both sides of the border. These tributaries play a crucial role in the hydrology and ecology of the region, and understanding them correctly is essential for accurate geographical knowledge.
