Pick up the correct statement from the following:

A. Gravity water is harmful to crops

B. Hygroscopic water remains attached to soil molecules by chemical bond

C. Capillary moisture held in the soil pores against gravity by surface tension, is utilized by plants

D. All the above

Answer: Option C

Solution (By Examveda Team)

Gravity water is harmful to crops because it moves quickly through the soil, often beyond the root zone, and does not provide effective moisture to the plants.

Hygroscopic water remains attached to soil molecules by a chemical bond, making it unavailable for plant absorption.

Capillary moisture, held in the soil pores against gravity by surface tension, is the form of water that plants utilize for their growth and survival.
