Solution
The correct option is C Emulsions
A colloidal system consists of two phases, one of which is spread throughout the other. The phase which is scattered is called the dispersed phase or the discontinuous phase. The phase in which dispersion happens is called the dispersion medium or the continuous phase. Either of these phases could be any of solids, liquids or gases.
When both the dispersion medium and the dispersed phase are liquids, the colloid has a specific name and is called 'emulsions'.
