Lyophilic solutions are more stable than lyophobic solutions. This is due to the fact that lyophilic colloids are extensively solvated, i.e., colloidal particles are covered by a sheath of liquid.
When a lyophilic colloid is added to a lyophobic colloid, the lyophilic colloid forms a layer around lyophobic particle and thus protect from an electrolyte.
Lyophilic colloids used for this purpose are called protective colloid.

Explanation:
Lyophilic and Lyophobic Colloids:
- Lyophilic colloids are colloids in which the dispersed phase has a strong affinity for the dispersion medium.
- Lyophobic colloids are colloids in which the dispersed phase has little or no affinity for the dispersion medium.
Protective Action in Colloids:
- Protective action in colloids refers to the ability of one colloid (A) to protect the other colloid (B) from coagulation or precipitation.
- In this case, A colloids (Lyophilic) perform protective action for B colloids (Lyophobic) due to their strong affinity for the dispersion medium.
- The protective action helps in stabilizing the colloidal system and preventing the aggregation of particles.
Correct Answer:
- Option B: Lyophilic and lyophobic
- The protective action is performed by lyophilic colloids for lyophobic colloids because the former can provide a stabilizing effect due to their affinity for the dispersion medium, which helps in preventing the coagulation or precipitation of the latter.
