Answer 1

The correct option is D Using underground water for irrigation

The capture, collection and storage of water for future use is known as water harvesting. It can be done by capturing runoff water from rooftops and floodwater from local streams, by building small earthen dams, sand and limestone reservoirs, by digging small pits and lakes, etc. The use of underground water for irrigation is one of the ways by which this stored water is used.
