Below Is a Diagram of Vapor Pressure Versus Composition for a Mixture

Below is a diagram of vapor pressure versus composition for a mixture of two liquids. The dark straight lines represent the vapor pressure of each pure liquid, while the gray curved line gives the vapor pressure of the mixture. Using this information, which of the following statements is true about the mixture?

A) The mixture is an ideal mixture that has no deviation from Raoult's Law.
B) The mixture is an ideal mixture with a positive deviation from Raoult's Law.
C) The mixture is not ideal and interactions between unlike molecules in solution are weaker than the interactions between like molecules in pure solution.
D) The mixture is not ideal and interactions between unlike molecules in solution are stronger than the interactions between like molecules in the pure solution.
E) The mixture is ideal and interactions between unlike molecules in solution are the same as the interactions between like molecules in the pure solution.
