Solution
The correct option is B Gum
The word meaning of lyophilic means ‘liquid-loving’ or ‘solvent- attracting’. This means that in this colloidal solution there is a strong attraction between the dispersed phase and dispersion medium.
Colloidal sols formed by mixing substances in a suitable dispersion medium are called lyophilic sols. These are quite stable. They are also known as reversible sols because the dispersion medium can be separated from the colloid by means of physical methods like evaporation. For e.g. gum, gelatin, starch, rubber, etc.
