Which soil is associated with the Deccan Trap region?

Correct answer: Black soil

The direct answer is option A: black soil. The Deccan Trap is a large region formed by ancient basaltic lava flows. When basalt weathers over a long period, it produces dark, clay-rich regur, commonly called black soil. This soil can hold moisture and is especially associated with cotton cultivation, although other crops can also grow in it. Step by step: lava cools into basalt; basalt weathers; dark clayey material accumulates; black soil develops. Option A is correct. Option B, sandy soil, is more associated with dry sandy regions and does not identify the Deccan Trap. Option C, coral soil, forms from coral or limestone-related coastal material, not basaltic lava. Option D, snow soil, is not a standard soil category associated with this region. The term “black” refers to the soil’s dark colour and properties, not simply to any dark-looking ground. Memory cue: Deccan Trap basalt gives black regur soil, famous for cotton.
