Which of the following does not show positive deviation from Raoult's law?

If vapour pressures of pure liquids $A$ and $B$ are $300$ and $800 \, torr$ respectively at $25 \, ^{\circ}C$. When these two liquids are mixed at this temperature to form a solution in which mole percentage of $B$ is $92$,then the total vapour pressure is observed to be $0.95 \, atm$. Which of the following is true for this solution?

When ethanol is mixed with cyclohexane,cyclohexane reduces the intermolecular forces between ethanol molecules. In this case,the liquid pair shows:

When two liquids $A$ and $B$ are mixed,their boiling point becomes greater than both of them. What is the nature of this solution?

An ideal solution has two components $A$ and $B$. If $A$ is more volatile than $B$,then the correct relation between mole fraction of $A$ in liquid $(X_A)$ and vapour phase $(Y_A)$ is:

Which of the following mixtures shows positive deviation from ideal behavior?
