Seeds when soaked in water, they imbibe because of
(a) OP inside the seed is low.
(b) OP of water is high.
(c) DPD of seed is very much low.
(d) Water potential gradient between the seed coat and water.

Dear student

Kindly refer the solution below to the asked query

The correct option is (d).
The seeds imbibe water when socked in water due to development of water potential gradient between water and seed coat. 
This is because the imbibition (absorption of water by solids) depends upon the water potential gradient between surface of adsorbent and imbibate (water here).
