Alluvial soil is the most common type of soil found in Jharkhand. It is a rich, fertile soil that is ideal for agriculture. Alluvial soil is formed from the deposition of sediments by rivers and streams. It is a mixture of sand, silt, and clay, and it is typically dark in color. Alluvial soil is well-drained and has a high water-holding capacity. It is also rich in nutrients, making it ideal for growing a variety of crops.
Red soil is a type of soil that is found in tropical and subtropical regions. It is a rich, reddish-brown soil that is formed from the weathering of granite and other igneous rocks. Red soil is well-drained and has a high water-holding capacity. It is also rich in nutrients, making it ideal for growing a variety of crops.
Black soil is a type of soil that is found in semi-arid and sub-humid regions. It is a dark, rich soil that is formed from the weathering of limestone and other carbonate rocks.

Laterite soil is a type of soil that is found in tropical and subtropical regions. It is a reddish-brown or yellow soil that is formed from the weathering of feldspar and other silicate rocks. Laterite soil is poor in nutrients and is not well-drained. It is also highly susceptible to erosion.
Therefore, the correct answer is: Alluvial soil.
