Answer & Explanation
Correct answer: (A) 4 1 2 3
The correct matching of morphological units with their associated river basins is:
The Rajgangpur-Panposh Uplands →Koel and the Sankh Rivers
- This upland region in Sundargarh district is drained by the South Koel and Sankh rivers, which together form the Brahmani at Vedvyas near Rourkela.
The Jharsuguda Uplands →Ib Basin
- The Jharsuguda uplands are primarily drained by the Ib River,a major tributary of the Mahanadi which drains this coal-rich region of western Odisha.
The Balangir-Titilagarh-Patnagarh Uplands → Northern Tel Basin
- These uplands in western Odisha are drained by the Tel River and its tributaries, which form part of the Mahanadi river system.
The Malakanagiri Uplands →The Sabari Basin
- The Malakanagiri uplands in southern Odisha are drained by the Sabari River, which is a major tributary of the Godavari River system.
