Correct option is C
The correct answer is (c) Both 1 and 2. · Statement 1 is correct: The Brahmaputra River originates from the Chemayungdung glacier in the Kailash range near Lake Mansarovar in Tibet. In Tibet, it is known as the Tsangpo, meaning "the purifier." Its major right bank tributary in Tibet is the Rango Tsangpo. · Statement 2 is correct: The river flows eastward across southern Tibet for around 1,200 km and then takes a sharp "U" turn near Namcha Barwa (7,755 m), where it carves a deep gorge in the Central Himalayas before entering India. It enters Arunachal Pradesh under the names Siang or Dihang and, after merging with the Dibang and Lohit rivers, it is called the Brahmaputra in Assam. Information Booster: · Journey through India: After entering India west of Sadiya in Arunachal Pradesh, the Brahmaputra flows southwest for about 750 km through the Assam Valley. Key Tributaries: · Left Bank: Dibang (Sikang), Lohit, Burhi Dihing, and Dhansari (South). · Right Bank: Subansiri (originates in Tibet), Kameng, Manas, and Sankosh. · In Bangladesh: The Brahmaputra enters Bangladesh near Dhubri in Assam and is called the Jamuna after joining with the Tista. It eventually merges with the Padma (Ganges) and flows into the Bay of Bengal. · Floods and Erosion: Known for its tendency to cause floods, channel shifting, and bank erosion due to heavy sediment load from its tributaries and the high rainfall in its catchment areas.
