Which of the following States/Union Territories is NOT a part of Indus River Basin?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Sikkim.
Sikkim is not a part of the Indus River Basin. The Indus River Basin primarily covers northwestern parts of India, including the states and union territories of Jammu and Kashmir, Himachal Pradesh, Punjab, Haryana, Rajasthan, and parts of Chandigarh. The basin is formed by the Indus River and its major tributaries—Jhelum, Chenab, Ravi, Beas, and Sutlej. In contrast, Sikkim is located in the northeastern part of India and lies within the Teesta River Basin, which is part of the larger Brahmaputra River system. Therefore, Sikkim has no geographical or hydrological connection with the Indus River Basin.
