C.
Both are true

Solution:

The correct answer is Both are true. Explanation: We can use Sprinkler irrigation for almost all crops except rice. Clay soil can easily form a crust and the infiltration rates are low. So, Sprinkler irrigation is not suitable. ?Additional InformationSandy soil, which is the low moisture retention soil, stores very less amount water and dries up quickly as they are highly porous and we need to irrigate more frequently, which is achieved by Sprinkler irrigation. Hint Big soil particle size = High porosity = High void space = High Infiltration loss = High frequency of Irrigation = Sprinkler system.
