The correct answer is: c) Alluvial soil.
Alluvial soil is the most common type of soil found in Punjab. 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 formed in tropical and subtropical regions. It is characterized by its reddish-brown color, which is due to the presence of iron oxide. Red soils are typically poor in nutrients and are not well-drained, making them less suitable for agriculture than alluvial soils.
Black soil is a type of soil that is formed in semi-arid regions. It is characterized by its dark color, which is due to the presence of organic matter. Black soils are typically rich in nutrients and are well-drained, making them ideal for agriculture.
Laterite soil is a type of soil that is formed in tropical regions. It is characterized by its high iron and aluminum content. Laterite soils are typically poor in nutrients and are not well-drained, making them less suitable for agriculture than alluvial soils.
