The correct answer is: Shows positive deviation from Raoult's law

For solution having positive deviation from Raoult's law

When an azeotropic mixture shows positive deviation, then vapour pressure of mixture is greater than that of either liquids at that temperature. Hence, mixture quickly boils i.e., its boiling point becomes less.
