With reference to river Teesta, consider the following statements.

1. The source of river Teesta is the same as that of Brahmaputra but it flows through Sikkim.

2. River Rangeet originates in Sikkim and it is a tributary of river Teesta.

3. River Teesta flows into Bay of Bengal on the border of India and Bangladesh.

Which of the statements given above is/are correct?

The correct answer is 2 only.

Let us analyze each statement step-by-step to understand why statement 2 is correct while statements 1 and 3 are incorrect:

1. Statement 1 is incorrect:
The Brahmaputra River originates from the Angsi Glacier (near Mount Kailash and Lake Manasarovar) in Tibet. In contrast, the Teesta River originates from Pahunri (or Tso Lhamo lake) in Sikkim, India. Therefore, the source of the river Teesta is not the same as that of the Brahmaputra.

2. Statement 2 is correct:
The Rangeet River is the largest river in Sikkim and originates in the Sikkim Himalayas. It is a major tributary of the Teesta River and meets the Teesta at Teesta Bazaar on the border between Sikkim and West Bengal.

3. Statement 3 is incorrect:
The Teesta River flows through the Indian states of Sikkim and West Bengal before entering Bangladesh, where it joins the Jamuna River (the main distributary/continuation of the Brahmaputra in Bangladesh). It does not directly flow into the Bay of Bengal on the border of India and Bangladesh; rather, it ultimately drains into the Bay of Bengal as part of the broader Ganges-Brahmaputra-Meghna river system well inside Bangladesh.

Hence, only statement 2 is correct.
