(A) Liquid is dispersed in liquid

(C) Sugar is dispersed in water

(C) Gas is dispersed in liquid

(D) Solid is dispersed in liquid

Answer 1

Explanation —

Milk is a type of colloidal solution (emulsion) in which both dispersed phase and dispersion medium are liquid.

i.e., liquid fats are dispersed in water.

Note : Foam is an example of gas dispersed in liquid dispersion medium.

Sols in water do not form a colloidal solution but form a true solution.

Sugar in water do not form a colloidal solution but form a true solution.
