The correct answer is D. Loamy soil.
Loamy soil is a mixture of sand, silt, and clay. It is the most ideal type of soil for maize cultivation because it is well-drained and has good water retention capacity. Maize plants need a lot of water to grow, so loamy soil provides the perfect environment for them.
Clay soil is too dense and does not drain well, which can lead to waterlogged conditions and root rot. Sandy soil is too loose and does not hold water well, which can lead to drought stress. Bal Sundari is a type of clay soil that is found in India. It is not ideal for maize cultivation because it is too dense and does not drain well.
In conclusion, loamy soil is the best type of soil for maize cultivation. It is well-drained and has good water retention capacity, which are essential for the growth of maize plants.
