Answer

Correct option: D.
Emulsion.
An emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids. In other words, an emulsion is a special type of mixture made by combining two liquids that normally don't mix. The word emulsion comes from the Latin word meaning "to milk" $($milk is one example of an emulsion of fat and water$).$ The process of turning a liquid mixture into an emulsion is called emulsification.
