Answer: The solution will deviate positively to Raoult's law. The correct option is A.

Explanation:

Raoult's law states that the partial pressure of components of a liquid mixture is equal to the vapour pressure of the individual components multipled by it's mole fraction. Since the solutions of the two liquids interacts less favourably than they do in the individual liquids, there will be less attraction. This will lead to a slightly high vapour pressure as the molecules easily escapes from the surface. Increased vapour pressure deviates Raoult's law positively.
