Solution

The correct option is C 98
Most of the water absorbed by plants is lost in transpiration. Transpiration is a very important physiological process. It sets the transpiration stream in plant and is also responsible for surface cooling of leaves. It has been estimated, that as much as 98 percent of water absorbed by plant roots is lost via stomatal transpiration.
