The predominant type of soil found in Bihar is:

Alluvial soil
Red soil
Black soil
Laterite soil

The correct answer is: a) Alluvial soil.

Alluvial soil is the most common type of soil found in Bihar. It is a type of soil that is formed by the deposition of sediments from rivers and streams. Alluvial soil is typically rich in nutrients and is well-drained, making it ideal for agriculture.

Red soil is a type of soil that is found in tropical and subtropical regions. It is typically reddish-brown in color and is rich in iron oxide. Red soil is not as fertile as alluvial soil, but it is still suitable for agriculture.

Black soil is a type of soil that is found in semi-arid and sub-humid regions. It is typically black or dark brown in color and is rich in organic matter. Black soil is very fertile and is well-suited for growing crops such as rice, wheat, and soybeans.

Laterite soil is a type of soil that is found in tropical and subtropical regions. It is typically reddish-brown or yellow in color and is rich in iron and aluminum oxides. Laterite soil is not as fertile as other types of soil and is prone to erosion.
