Answer: A. Water must be available for plants to transpire and the air cannot be saturated with humidity.
Explanation:
Evapotranspiration is the sum of evaporation and transpiration. Evaporation is the loss of water from the earth surface or ground water table and transpiration is lost of water from plant surfaces. Plant absorps water from the soil through the root and it is transport by xylem to various body cells.
When the humidity is high and the air is saturated with water the rate of evapotranspiration is low but at a low humidity the rate of evaporation is high until the air is saturated.
Temperature also have a major role in transpiration. When the temperature is high the plant stomata is open which favours water Loss from plant but when the temperature is low plant closes their stomata in response to temperature change.
