The correct option seems to be D as A and B are also true.
Hygroscopic water is held as a thin film of low chemical bond around the soil particle. Correct me, if I am wrong.

Yes, all are correct.
Since gravity water is held for 1-3 days by soon and also prevent aeration of air for the crop. So this water is harmful to crops.
