Statements 1 and 2 are correct, while statement 3 is incorrect.
Statement 1 is correct. The Brahmaputra River originates in Tibet where it is known as Tsangpo. It flows eastwards, makes a sharp turn south at the Namcha Barwa bend, and enters Arunachal Pradesh, India, where it is called Siang or Dihang. Statement 2 is correct. The Ganga basin is the largest river basin in India. The Godavari basin is the second largest, covering approximately 10% of the total geographical area of India. Statement 3 is incorrect. The Chambal and Betwa rivers are major tributaries of the Yamuna River. The Yamuna is a major tributary of the Ganga, joining it at Prayagraj (Allahabad) in Uttar Pradesh. Therefore, Chambal and Betwa join the Yamuna, not the Ganga directly.
Major right-bank tributaries of the Ganga include the Yamuna, Son, and Damodar (though Damodar joins the Hooghly, a distributary). Major left-bank tributaries include the Ghaghara, Gandak, and Kosi.
