Best answer

Correct Answer is: (b) Gum 

• 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.
