B) Keeping tap on while bathing
C) Washing your car daily
D) Using excess water in the kitchen

Answer 1

Hint: Water-wise habits are habits that are necessary to conserve water and minimise the misuse of water. Optimal conservation can be achieved with habits with judicious use of water.

Step by step answer: Clean water is a limited resource and is not renewable as clean water does not remain clean again by reuse. Water is an important part of the human body. Up to \[75\% \] of the body is filled with water, and thus drinking water is very essential for the body to perform various biological functions. Without water, there is no survival for the living organisms. Water scarcity can be dangerous and thus, water conservation is very important. The water is used in other important things like household cleaning, bathing, cooking, drinking, etc. Thus, the water should be efficiently used and conserved. Foodgrains like rice require a lot of water than other vegetables or grains. Scarcity of water would affect food availability too. Availability of water is too less than it seems. Out of \[70\% \] of water present on the Earth, only 0.03% of freshwater is potable. Water conservation also helps in saving the energy which is used to pump from the central source of water to houses. Simple habits can help to conserve water, such as saving rainwater for other cleaning activities in a catchment area, closing tap when not in use, etc. Also, household practices like mopping instead of pouring water to clean the floor.
Hence, the correct answer is option A.

Note: Effects of water wastage are as follows:
i. Wasting water may limit its availability to other communities, especially in areas where water shortage is common.
ii. An arid ecosystem may suffer when water is wasted.
