Solution

The correct options are
A Loss of water due to evaporation
B Seepage of water into the ground
D Improper distribution of water
Crops were traditionally watered through canals. But a lot of water is lost due to evaporation and seepage into the ground. Canal irrigation also leads to improper distribution of water to plants.

But nowadays, improved methods of irrigation like sprinkle irrigation, drip irrigation are used. They provide enough water to the plants with a minimal amount of wastage.
