(a) Dust an aerosol

(b) Mud a sol

(c) Styrofoam a solid foam

Explanation:

A colloid consists of a homogeneous mixture of substances having particle sizes ranging 1 to 1000 nano-meters

There are different types of colloids including

Emulsion which is a colloids consisting of two liquids

Sol this consists of solid particles dispersed in a liquid

Foam this are colloids consisting of gas particles dispersed in a liquid or solid and

Aerosol Which are liquids particles dispersed in a gas

Mud Consists of solids dispersed in liquid therefore it is a sol

Styrofoam consist of a gas dispersed in a solid as such it is a solid foam
