C) Agricultural irrigation

Explanation:

Humans use more freshwater in agricultural irrigation. Agriculture needs freshwater as most of the plants need fresh water for their survival. Very few plants such as cottons, cereals, alfalfa, some grasses can live in saline water/soil.  

Most of the edible crops need fresh water for their growth and development. Agriculture needs regular irrigation for betterer yield.

Agriculture means exporting water within the foods. For example, rice needs a maximum of water.  

The saline waters can be used for the industrial, mining process, and electricity production. People use freshwater for household purposes and agricultural use. These freshwater draws from surface water and groundwater. The percentage of surface water used for irrigation is about 63. It is taken from rivers, wells, from undergrounds. As the population increase, the demand for freshwater also increases which put pressure on all type of freshwater.
