Verified by Experts

The correct answer is:

Lyophilic colloids have a unique property of protecting lyohobic colloid. When a lyophilic sol is added to the lyohobic sol, the lyophilic particles form a layer around lyophobic particles and thus protect the latter from electrolytes. Lyophilic colloids used for this purpose are called protective colloids.
