Correct Option
The correct option is A-2, B-1, C-3, D-4
Explanation
The drainage system of India is primarily divided into the Himalayan drainage system and the Peninsular drainage system. Major rivers such as the Indus, Ganga, and Brahmaputra form the Himalayan system, receiving tributaries from both the Himalayan ranges and the Peninsular plateau.
Detailed Analysis
- A. Lohit: The Lohit River is a significant tributary of the Brahmaputra. It originates in eastern Tibet and flows through Arunachal Pradesh before joining the Brahmaputra (Siang) in Assam.
- B. Zaskar: The Zaskar River is a tributary of the Indus. It drains the Zaskar Range in the Ladakh region and joins the Indus River near Nimmu.
- C. Betwa: The Betwa River originates in the Vindhya Range (Peninsular India) and flows northwards. It is a tributary of the Yamuna River, which in turn is the largest tributary of the Ganga. Therefore, the Betwa is part of the Ganga drainage system.
- D. Ghaghara: The Ghaghara River is a major left-bank tributary of the Ganga. It originates in the glaciers of Mapchachungo near Lake Manasarovar and joins the Ganga at Chhapra, Bihar.
Matching:
- A (Lohit) matches with 2 (Brahmaputra).
- B (Zaskar) matches with 1 (Indus).
- C (Betwa) matches with 3 (Ganga).
- D (Ghaghara) matches with 4 (Ganga).
Key Takeaway: The Lohit feeds the Brahmaputra; the Zaskar feeds the Indus; the Betwa (via Yamuna) and Ghaghara are key components of the Ganga river system.
