The correct answer is: c) Alluvial soil
Alluvial soil is the most dominant soil type found in Tamil Nadu. 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 organic matter, making them ideal for agriculture. They are also well-drained and have a good water-holding capacity.
Black soil is a type of soil that is rich in organic matter and iron oxide. It is found in the Deccan Plateau of India, including parts of Tamil Nadu. Black soil is well-suited for growing crops such as cotton, sugarcane, and rice.
Red soil is a type of soil that is rich in iron oxide. It is found in the drier parts of India, including parts of Tamil Nadu. Red soil is not as fertile as black soil, but it is still suitable for growing crops such as millet, sorghum, and pulses.
Laterite soil is a type of soil that is formed in tropical and subtropical regions. It is rich in iron and aluminum oxides, and it is typically red or yellow in color. Laterite soil is not very fertile, and it is prone to erosion.
