Answer: C

A lysimeter is used to measure Evapotranspiration.

A lysimeter is a tank of soil with growing vegetation, set in the field so that its conditions match the surroundings. By measuring the water added (rain and irrigation) and the water draining out, and weighing the tank, the water lost by evaporation and transpiration is found.

Humidity is measured with a hygrometer or psychrometer, infiltration with an infiltrometer, and wind speed with an anemometer.
