Hint: The blotting paper is a thin and smooth paper which grants an infant thicker liquid like ink to absorb, so it involves capillary action. That is required for liquids flow that means to dissolve things.
Complete step by step answer:
Due to the forces of adhesion, cohesion and surface tension, capillary action is explained as the movement of the liquid within the arena of spongy material. It appears due to the sticky nature of liquid like ink.
Basically, capillary action is defined as the capability of a liquid to flow in a cramped arena without the compensation of peripheral forces i.e. gravity. The life examples of capillary action are that falling the liquids between the hairs of paint brush, liquids flow in biological cells and flow in a thin tube.
Capillary action appears because of intermolecular forces between the liquid and enclosing solid surfaces. The amalgamation of surface tension and clinging forces between the liquid and storage wall move to thrust the liquid when the diameter of the tube is too short.
There is ample mass of liquid for gravitational forces to bury these intermolecular forces due to adhesion appearing between the fluid and solid focal line which is ripping the liquid column.
Hence, the absorption of ink by blotting paper involves the capillary action process.
Since the capillary action process is involved in this hence the other answers given in the options are incorrect.
So, the correct option is b.
Note: Always remember that the capillary action easily absorbs the liquid by thin medium. Note that Insertion of capillary in any spongy field contributes to dynamic process and discharge hollow tubes.
