Option (A)

Explanation:

The freshwater covers a tiny portion on the earth's surface and is only about 3% of the total water body present on earth. This includes the water present in the rivers, lakes, ponds, glaciers, and ice.

This freshwater is highly contaminated mostly due to the human activities causing water pollution. The waste materials released from the mines, factories, and industries are mixed up with the nearby river water, as a result of which the water is polluted. In addition to this, the occurrence of acid rain also affects the quality of the freshwater and also the sewage waste materials released from the people's house are causing damages to the water.

This water pollution must be controlled and reduced in order to protect the water sources and keep them clean and hygienic. This is one way to increase freshwater availability on the earth's surface.
