The correct answer is Brahmaputra.
Majuli is a large river island located in the Brahmaputra River in Assam, India. It was the world’s largest river island for a period, though its size has decreased significantly due to erosion. The island is formed by the Brahmaputra river in the south and the Kherkutia Suti, an anabranch of the Brahmaputra, joined by the Subansiri River in the north.
Majuli is culturally significant as the hub of Assamese neo-Vaishnavite culture, with numerous Satras (monasteries) located there. The island faces severe environmental challenges, primarily riverbank erosion, which has led to a substantial reduction in its area over the past few decades. Efforts are ongoing for its conservation.

Both statements about the Brahmaputra River are correct.
1. It rises in Tibet, near Lake Mansarovar: The Brahmaputra, known as Yarlung Tsangpo in Tibet, originates from the Chemayungdung glacier located in southwestern Tibet, near Lake Mansarovar.
2. It takes a “U” turn near Namcha Barwa and enters India through a gorge: The Yarlung Tsangpo flows eastward through Tibet and takes a sharp southward bend (a hairpin bend often described as a “U” turn) around the peak of Namcha Barwa (7,756 m) in the Eastern Himalayas. It then enters Arunachal Pradesh in India through a deep gorge (Dihang Gorge), where it is known as Siang or Dihang.
The Brahmaputra is one of the major trans-boundary rivers of Asia, flowing through China (Tibet), India, and Bangladesh. Its origin and dramatic entry into India through the Himalayan gorge are key geographical features.
In India, the Brahmaputra is known by different names: Siang or Dihang in Arunachal Pradesh, and Brahmaputra in Assam. It is joined by several tributaries, including Dibang and Lohit, to form the main Brahmaputra river in Assam. It finally flows into Bangladesh where it is known as Jamuna and merges with the Padma (Ganga) before draining into the Bay of Bengal.

The correct answer is C) River Mahananda.
The Brahmaputra River has numerous tributaries flowing from the Himalayas and the hills of the Northeast. River Manas, River Kameng (also known as Jiabharali), and River Subansiri are all major left-bank or right-bank tributaries of the Brahmaputra in India and Bhutan. The River Mahananda originates in the Darjeeling hills and flows south through West Bengal and Bihar before joining the River Ganges (Padma) in Bangladesh. It is a tributary of the Ganges system, not the Brahmaputra system.
The Brahmaputra’s major tributaries include Dibang, Lohit, Subansiri, Kameng, Manas, Sankosh, Teesta, and Dhansiri. The Mahananda River is an important river in the Ganges basin, known for its fertile alluvial plains.

The Brahmaputra river, known as Tsangpo in Tibet, flows eastward parallel to the main range of the Himalayas. Near the easternmost extent of the Himalayas, it encounters the peak of Namcha Barwa (7782m) in the Tibetan region. At this point, the river takes a sharp U-turn, forming a deep gorge (the Yarlung Tsangpo Grand Canyon), and enters Arunachal Pradesh in India, where it is known as Siang or Dihang, before being joined by other tributaries and becoming the Brahmaputra.
The Brahmaputra (Tsangpo) river makes a significant bend around the peak of Namcha Barwa before entering India.
The other rivers mentioned do not follow this course. The Ganga originates in the Himalayas in Uttarakhand and flows through the plains. The Teesta flows through Sikkim and West Bengal into Bangladesh, joining the Brahmaputra. The Barak River flows through Assam and Manipur into Bangladesh, forming part of the Surma-Meghna river system.

The correct arrangement of the Brahmaputra tributaries from west to east is Teesta, Sankosh, Subansiri, Lohit.
Arranging tributaries of a river from west to east requires knowledge of their geographical locations and where they join the main river channel. Teesta (2) joins the Brahmaputra (Jamuna) in Bangladesh, west of the confluence point of the main Brahmaputra entering Bangladesh. Sankosh (4) forms part of the border between Assam and West Bengal, joining the Brahmaputra in Assam. Subansiri (3) is a major northern tributary joining the Brahmaputra further east in Assam. Lohit (1) is an eastern tributary that joins the Brahmaputra near Sadiya, marking the easternmost extent of the Brahmaputra in India before it turns south.
The Brahmaputra river, known as Yarlung Tsangpo in Tibet, flows through Arunachal Pradesh (where it’s called Siang), then Assam, and finally enters Bangladesh as Jamuna. Major tributaries include the Dibang, Lohit, Subansiri, Kameng, Manas, Sankosh, and Teesta. The Manas river joins the Brahmaputra between Sankosh and Subansiri. The order from west to east is roughly Teesta, Sankosh, Manas, Subansiri, Dibang, Lohit. Among the given options, 2-4-3-1 (Teesta, Sankosh, Subansiri, Lohit) follows the correct relative west-to-east sequence.
