@Mohit and that chemical bond is called Adhesion is the same thing,

All the option seems correct because;

1) The Gravity water affects plants due to water clogging and air circulation.
2) Hygroscopic water remains in the soil and cannot be utilized by soil.
3) Capillary water is the water plants use for photosynthesis mostly.
So, the right Answer is D.

I think the correct option is C because hygroscopic water can be removed by heat.
