Correct answer is (a) Emulsions cannot be separated into their constituent liquids

Explanation: Emulsions can be separated into their constituent liquids by boiling, freezing, centrifuging, electrostatic precipitation by adding large amounts of the electrolyte to precipitate out the dispersed phase or by chemical destruction of the emulsifying agent.
