If the clues are black soil, cotton, and basaltic lava, which landform is correct?
Answer and explanation
Correct answer: Deccan Plateau
The governing concept is the link between parent rock, soil formation and regional agriculture. Much of the Deccan Plateau is underlain by basaltic lava flows associated with the Deccan Traps. Weathering of this basalt, together with local climatic conditions, has produced extensive black or regur soil. This soil retains moisture and is especially suitable for cotton, so the combined clues point clearly to option A, the Deccan Plateau. The Khasi Hills are a northeastern hill system, Himadri is the highest Himalayan range, and the Aravalli is an ancient mountain system. None of those alternatives is identified by the specific basalt–black soil–cotton association.
