Answer:
Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
Answer:
Option C
Explanation:
As we know that
Relative humidity (RH) is defined as the ratio of amount of water vapor present in a given sample of air to the maximum amount of water that can be absorbed by the same sample of air to attain saturation at a particular temperature
.
Thus,

Where X represents the current amount of water vapor present in a given sample of air
and Y represents the maximum amount of water that can be absorbed by the same sample of air to attain saturation at a particular temperature
Substituting the given values in above equation we get -

Hence, option C is the correct answer
