Solution

The correct option is A ΔHmix>0
On adding cyclohexane to ethanol . Its molecules get in between the molecules of ethanol thus breaking the hydrogen bonds and reducing ethanol - ethanol interaction .
Thus will increase the vapour pressure of the solution and result in positive deviation from Rouault's law.
