The correct answer is C. Distillation.
Decantation is the process of separating a liquid from a solid precipitate by pouring off the liquid without disturbing the precipitate. Evaporation is the process of a substance changing from a liquid to a gas
or vapor. Sublimation is the process of a solid changing directly into a gas or vapor without passing through the liquid state.Distillation is the process of separating a mixture of liquids by boiling them and then collecting the vapors. The vapors are then
condensed back into a liquid, which is a pure form of one of the original liquids.In the case of a mixture of water and alcohol, the water will boil at a lower temperature than the alcohol. This means that when the mixture is heated, the water will vaporize first. The vapor will then be condensed back into a liquid, which will be pure water. The alcohol will remain in the original mixture.
Distillation is a common method for purifying liquids. It is also used to separate different components of a mixture. For example, crude oil is distilled to produce gasoline, diesel fuel, and other products.
