Answer: Option B

In India, the red soil is mostly found in Tamil Nadu state.
Red soil is a type of soil that typically develops in warm, temperate and humid climates and comprises approximately 13% of Earth's soils. It contains thin organic and organic-mineral layers of highly leached soil resting on a red layer of alluvium.
It is usually low in nutrients and humus and can be difficult to cultivate due to its low water holding capacity, however, the fertility of these soils can be optimized with liming and other farming techniques.
