Right answer is (d) It is independent of the crop type and its growth

For explanation I would say: Consumptive use coefficient (k) = evapotranspiration (Cu or Et) / pan evaporation (Ep). It is different for different crops, varies with crop growth and is different at different crop stages for the same crop.
