Hint: To answer this question, you must know what saline water is and recall its properties and uses. Saline water is salty water and is the most abundant type of water on the earth as all the water in oceans and seas is saline. The high amount of salt content in saline water makes it tough to use for most of the purposes.
Complete step by step solution
Saline water contains a high amount of salt. Thus, it cannot be used for washing clothes. Also the high amounts of salt are unsuitable for the human body. Thus, it cannot be used for drinking. Although one might think that saline water can be used for agricultural purposes, it is not quite possible. Irrigating the agricultural fields with saline water results in the accumulation of high levels of salt in the root zones of the crops.
Thus salt water cannot be used for any of the above purposes or any other common domestic purposes. For all these purposes and other domestic uses we use fresh water. However freshwater is very scarce on the surface of earth as compared to saline water.
The correct answer is D.
Note
More than half of the earth’s surface is covered with water but majority of that water is not fit for use as it is saline. Fresh water is fit for use but is less in amount. The increasing scarcity of salt water is a cause of worry and it is important for us to conserve fresh water.
