The question asks to match map labels (A, B, C, D) representing major world drainage basins with their names. Assuming a standard world map showing major river basins: 1. Label A typically represents South America east of the Andes. The largest basin here is the Amazon, but among the options, the Parana basin is a major one in the southern part of this region. (A likely matches 3) 2. Label B typically represents the Indian subcontinent/Southeast Asia. The Ganga-Brahmaputra basin is the most prominent one here. (B likely matches 1) 3. Label C typically represents Southern Africa. The Zambezi river basin is a major feature here. (C likely matches 4) 4. Label D typically represents the area west of the Indian subcontinent (Pakistan/Central Asia). The Indus basin is the major system here. (D likely matches 2) Combining these: A-3, B-1, C-4, D-2.
