Of all the water on the earth, only about 3% is fresh water. 68% of all the freshwater is frozen as glaciers and is unavailable
AleksAgata [21]

Answer:

The correct answer is statement A.

Explanation:

The procedure of purifying ocean water, that is, the saline water so that it can become suitable for drinking is termed as desalination. Almost 70 percent of the Earth is covered with water and of this only 3 percent is used for drinking purposes. On a huge scale, the process of desalination would require the boiling of water, which would eventually require an enormous amount of energy.  

Reverse osmosis and electro-dialysis are the methods used for desalination. However, these procedures are very costly and cannot be performed on a huge level as it can affect the economy of various countries.
