Answer: D

Explanation:

The evapotranspiration rate is the amount of water loss in a vegetated surface in units of water depth, such as millimeters or inches. It is a measure of the water demand of the plants and the climate conditions. It is used to calculate the baseline water use for irrigation in the Outdoor Water Use Reduction credit.
