Solution

The correct option is B Transpiration and absorption ratio
Potometer is an instrument for measuring the rate of transpiration by shoots through measuring the rate of their water absorption, as the two are nearly equal. There are several types of potometers described in literature e.g., Ganong's potometer, Farmers potometer, Bose potometer, Simple or Darwin potometer.
