The correct answer is: Alluvial soil.
Alluvial soil is the most dominant type of soil in the Telangana region. It is a type of soil that is formed by the deposition of sediments from rivers and streams. Alluvial soils are typically rich in nutrients and are well-drained, making them ideal for agriculture.
Red soil is a type of soil that is rich in iron oxide. It is typically found in tropical and subtropical regions. Red soils are not as fertile as alluvial soils, but they are still suitable for agriculture.
Black soil is a type of soil that is rich in organic matter. It is typically found in semi-arid and sub-humid regions. Black soils are very fertile and are well-suited for growing crops such as rice, wheat, and cotton.
Laterite soil is a type of soil that is formed by the weathering of rocks in tropical and subtropical regions. Laterite soils are typically poor in nutrients and are not well-drained. They are not suitable for agriculture, but they are used for other purposes such as brickmaking and road construction.
