A. (b) and (c)
Step-by-step solution
Absorption of fluid by a colloid or porous solid that often results in swelling is known as imbibitions. Two conditions are prerequisites for imbibition, i.e.,
a) a water potential gradient must exist between the surface of the absorbent and the liquid imbibed, and
b) an affinity must exist between the component of the absorbent and the imbibed substance.
a) a water potential gradient must exist between the surface of the absorbent and the liquid imbibed, and
b) an affinity must exist between the component of the absorbent and the imbibed substance.
