Solution
The correct option is C Capillary water
Capillary water is found in the micropores of the soil. It is held on the soil particles by surface forces, against gravity. The molecules of the capillary water are mobile and are present in liquid state. Thus, the water molecules can evaporate at ordinary temperature. Though it is held firmly by the soil particle, plant roots are able to absorb it. The force which controls capillary water ranges from -1/3 to -30 bars. Hence, the answer is C.
