D
All of the above
Solution:
Clayey soil is useful for growing crops as it has good water retaining capacity, is rich in organic matter and has small size particles. There are very small particles in clayey soil. Due to their tight packing, these particles are able to hold water. Organic matter is also abundant in clayey soil. A fertile soil rich in organic matter and good at retaining water is ideal for growing crops such as wheat, gram, and paddy.
