Option : (A) Shows a positive deviation from Raoult's law.

When solution shows a positive deviation from Rault's law, it means, there is very weak intermolecular forces between particle in solution, than those present in the ideal solution.

At a specific composition the boiling point of azeotrope solution has lower than that of either of component.
