Solution

The correct option is D

Transpiration


Transpiration is the process of evaporation of water through tiny openings in leaves known as stomata. This evaporation creates a suction pull as when we drink any fluid using a straw. This suction is strong enough to pull water high up to the tips of even the tallest of trees. Transpiration also helps in cooling the plants.
