The correct options are
A Not wasting water at home and elsewhere.
B Government involvement in providing viable solutions.
C Storing water in tanks or dams.
D Planting more trees in and around the affected region.
Doing little things such as not leaving taps open for very long can help save water. If regions are prone to drought, water can be stored in tanks or dams. This water can be used during a crisis. Planting more trees in such drought-prone areas can help bring rainfall. The government should also take necessary measures to help farmers, whose lives depend a lot on the availability of an adequate amount of water for their crops.
