Concept:Distillation separates liquid-liquid mixtures by using differences in boiling points.
Explanation:A liquid-liquid mixture contains two or more liquids mixed together.
Filtration is used to separate an insoluble solid from a liquid, so it is not correct.
Evaporation separates a dissolved solid from a liquid, not two liquids.
Sublimation is used for separating sublimable solids from non-sublimable substances.
Distillation involves heating the mixture so that one liquid boils and turns into vapor.
The vapor is then cooled and condensed back into a liquid, leaving the other liquid behind.
For example, ethanol can be separated from a mixture of ethanol and water by fractional distillation.
Answer:Distillation (Option D).
