‘A’ and ‘B’ are two volatile liquids.A mixture of ‘A’ and'B' is prepared.A graph is plotted between vapour pressure of liquid mixture and mole fraction. The following plot is obtained

From the graphical represent identify the liquid mixture

From the graph it is evident that 

A) ${\mathrm{p}}_{\mathrm{total}}>{\mathrm{p}}_{\mathrm{A}}+{\mathrm{p}}_{\mathrm{B}}$

B) ${\mathrm{p}}_{\mathrm{A}}>{\mathrm{p}}_{\mathrm{A}}^{\mathrm{o}}{\mathrm{x}}_{\mathrm{A}}$

C) ${\mathrm{p}}_{\mathrm{B}}>{\mathrm{p}}_{\mathrm{B}}^{\mathrm{o}}{\mathrm{x}}_{\mathrm{B}}$

The liquid mixture shows positive deviations from Raoult's law.

The H-bonds of ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ are weakened by the addition of ${\mathrm{CS}}_2$. 

A-B interactions are weaker than A-A and B-B interactions.
