The correct answer is: c) Alluvial soil.

Alluvial soil is a type of soil that is formed by the deposition of sediment from rivers and streams. It is a very fertile soil and is ideal for growing crops. Punjab experiences alluvial soil primarily because it is located in the Indo-Gangetic plain, which is a vast alluvial plain that is formed by the Indus and Ganges rivers.

Black soil is a type of soil that is rich in organic matter and is dark in color. It is found in the Deccan Plateau of India. Red soil is a type of soil that is rich in iron oxide and is red in color. It is found in the central and southern parts of India. Laterite soil is a type of soil that is formed in tropical and subtropical regions. It is a very poor soil and is not suitable for growing crops.

Here is a table that summarizes the characteristics of each type of soil:

| Soil type | Characteristics | |---|---| | Alluvial soil | Fertile, formed by the deposition of sediment from rivers and streams | | Black soil | Rich in organic matter, dark in color | | Red soil | Rich in iron oxide, red in color | | Laterite soil | Poor, formed in tropical and subtropical regions |
