Answer: (B)

Transpiration is a physiological process while evaporation is a physical process

Transpiration is a physiological process because it is a metabolic activity which occurs inside plants which is a living system. It is the process of loss of water in form of water vapor from the stomata of the plant. Evaporation is a physical process and occurs in any free surface whether living or non living. It is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature or pressure.
