Solution
The correct option is D Sorption
Adsorption:
The substance is concentrated only at the surface and does not penetrate through the surface to the bulk of the adsorbent.
Absorption:
The substance is uniformly distributed throughout the bulk of the solid.
When both absorption and adsorption, of the same substance, take place simultaneously, it is called sorption.
Example: Chalk in ink solution
