Options:

B .  hygroscopic water
C .  capillary water

Answer: Option C
Answer: (c)Capillary water is retained on the soil particles by surface forces. It is held so strongly that gravity can not remove it from the soil particles. The molecules of capillary water are free and mobile and are present in a liquid state. Plant roots are able to absorb it. Capillary water is, therefore, also known as available water.
