Right choice is (d) The porosity of the soil

The best explanation: Evaporation loss is not that significant and may range from 2-3% of the total canal discharge. The rate of loss depends mainly on temperature and humidity of the region, prevailing wind velocity and the area of water surface exposed to the atmosphere.
