Solution

The correct option is C ΔHmix<0
Maximum boiling azeotropes are those which boil at a higher temperature than the boiling point of each component in a pure state, e.g., 68 % nitric acid and 32 % water by mass.
Consequently, Azeotropic mixture has lower vapour pressure as compared to vapour pressure of each component in pure state.
