1. C: liquid in solid; M: liquid in liquid; S: solid in gas
2. C: solid in liquid; M: liquid in liquid; S: gas in solid
3. C: liquid in solid; M: liquid in solid; S: solid in gas
4. C: solid in liquid; M: solid in liquid; S: solid in gas

Answer 1

Correct Answer - Option 1 : C: liquid in solid; M: liquid in liquid; S: solid in gas

Concept:

Dispersed phase	Dispersion medium	Type of colloid	Examples
Liquid	Solid	Gel	Cheese(C), butter, jellies
Liquid	Liquid	Emulsion	Milk (M), hair cream
Solid	Gas	Aerosol	Smoke(S), dust

 

Thus, C: liquid in solid, M: liquid in liquid and S: solid in gas.
