The answer is C. Distillation. Distillation is a common process for separating liquid mixtures by using the principle of volatility and boiling point. For a liquid mixture with two liquid components A and B, A will have a lower boiling point or higher volatility than B. By boiling the mixture at the boiling point of component A, only component A will evaporate from the mixture. The evaporated gas will then be cooled to condense component A back to a liquid.
