Consider the following pairs matching tributaries to their main river systems:
Which of the pairs given above is/are correctly matched?
- A(a), (b) and (c)
- B(a) and (b) only
- C(a) and (c) only
- D(c) only
Solution & Step-by-step Explanation
Pair (a) is incorrectly matched because the Chambal River is a principal tributary of the Yamuna River, not the Narmada. Pair (b) is incorrectly matched because the Son River is a major right-bank tributary flowing directly into the Ganga River, not the Yamuna. Pair (c) is correctly matched as the Manas River is a significant right-bank transboundary tributary of the Brahmaputra River in Assam.
