The correct statement about the mixture of phenol and aniline are

In the mixture of phenol and aniline, the intermolecular hydrogen bonding between phenolic proton and lone pair on N-atom of aniline is stronger than the respective intermolecular hydrogen bonding between two same  molecules. Thus, their mixture shows negative deviation from Raoult's law.
For such mixtures,${\mathrm{\Delta H}}_{\text{mix }}<0\text{ and }{\mathrm{\Delta V}}_{\text{mix }}<0$
It forms a maximum boiling azeotrope.
