The combined clues black soil, cotton, and basaltic rocks point to which region?
Answer and explanation
Correct answer: Deccan Plateau
The correct answer is B, the Deccan Plateau. Much of the Deccan is underlain by basaltic lava flows, and the weathering of this basalt has produced extensive black soil, also called regur. This soil has a high clay content, retains moisture effectively, and is particularly suitable for cotton cultivation when other conditions are favourable. The combination of basalt, black soil, and cotton is therefore a classic geographical association with the Deccan Trap region of peninsular India. The Khasi Hills are mainly linked with the Meghalaya uplands and very heavy rainfall; Himadri is the highest Himalayan range; and the Aravalli is an old fold mountain system with different rock and soil associations. Hence all three clues converge on option B.
