Solution

The correct option is C charge on the particles
Lyophillic colloids are liquid loving colloids (i.e. Lyo means solvent and philic means loving). when these colloids are mixed with a liquid, it generates high force of attraction between colloidal particles and liquid. Due to this, a very stable lyophilic colloid is formed due to charge on the particles.
Option A is the correct answer.
