The correct answer is: A) Black soil
Black soil is the most common type of soil found in the Deccan Plateau region of Karnataka. It is a rich, loamy soil that is ideal for growing crops such as rice, sugarcane, and cotton. Black soil is formed from the weathering of basalt rocks, and it is characterized by its dark color, high organic matter content, and good water retention capacity.
Red soil is another type of soil that is found in the Deccan Plateau region. It is a lighter-colored soil that is less fertile than black soil. Red soil is formed from the weathering of granite rocks, and it is characterized by its high iron content.
Alluvial soil is a type of soil that is found in river valleys. It is a fertile soil that is made up of sediments that have been deposited by rivers. Alluvial soil is ideal for growing crops such as rice, wheat, and barley.
Laterite soil is a type of soil that is found in tropical and subtropical regions. It is a reddish-brown soil that is low in nutrients and has poor drainage. Laterite soil is not suitable for growing crops, but it can be used for other purposes such as brickmaking.
