b.

c.
cool the air through evaporative cooling
d.
turn sea water into freshwater

The correct answer is - C. cool the air through evaporative cooling.

The water misters are crucial and of extreme importance for the drip irrigation systems, especially in the regions that are hot and drier. The misters are very important because through the pushing under pressure of the water, it manages to maximize the water supply over a much wider area, than what could be accomplished with the standard irrigation systems. Also, they manage to cool of the air around the plants, and that is of great benefit in the regions that are hot and dry for prolonged periods of time. The water misters are in the shape of hoses that are attached near the plants, and they have little holes on them, so the water doesn't rush through, but falls in a drop by drop manner.
