Correct Option :
The correct option is (1) A-3, B-1, C-2, D-4.
- Basin A represents the Parana River basin in South America. The Parana River is a major river in south-central South America, flowing through Brazil, Paraguay, and Argentina.
- Basin B represents the Ganga-Brahmaputra River basin in South Asia. This basin is formed by the confluence of the Ganga and Brahmaputra rivers, draining a large portion of India, Bangladesh, Nepal, and Bhutan.
- Basin C represents the Indus River basin in South Asia. The Indus River originates in the Tibetan Plateau and flows through India and Pakistan before emptying into the Arabian Sea.
- Basin D represents the Zambezi River basin in Southern Africa. The Zambezi is the fourth-longest river in Africa, flowing through Zambia, Angola, Namibia, Botswana, Zimbabwe, and Mozambique.
Incorrect Options:
- Options (2), (3), and (4) are incorrect as they misidentify one or more of the drainage basins. For instance, option (2) incorrectly assigns Ganga-Brahmaputra to A and Parana to B. Option (3) incorrectly assigns Ganga-Brahmaputra to A and Indus to C. Option (4) incorrectly assigns Ganga-Brahmaputra to B and Zambezi to C. The correct geographical locations and corresponding river basins are crucial for accurate identification.
