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

Vapour pressure of pure acetone and chloroform at $328 \, K$ are $741.8 \, mm \, Hg$ and $632.8 \, mm \, Hg$ respectively. Assuming that they form an ideal solution over the entire range of composition,plot $p_{total}$,$p_{chloroform}$,and $p_{acetone}$ as a function of $x_{acetone}$. The experimental data observed for different compositions of the mixture is:

$100 \times x_{acetone}$	$0, 11.8, 23.4, 36.0, 50.8, 85.2, 64.5, 72.1$
$p_{acetone} / mm \, Hg$	$0, 54.9, 110.1, 202.4, 322.7, 405.9, 454.1, 521.1$
$p_{chloroform} / mm \, Hg$	$632.8, 548.1, 469.4, 359.7, 257.7, 193.6, 161.2, 120.7$

Raoult's law is obeyed by each constituent of a binary liquid solution when

Formation of a solution from two components can be considered as
$(i)$ Pure solvent $\to$ separated solvent molecules $\Delta H_1$
$(ii)$ Pure solute $\to$ separated solute molecules $\Delta H_2$
$(iii)$ Separated solvent and solute molecules $\to$ solution $\Delta H_3$
Solution so formed will be ideal if

Which of the following mixture$(s)$ show$(s)$ positive deviation from Raoult's law at $35^{\circ}C$?
$(A)$ Carbon tetrachloride + methanol
$(B)$ Carbon disulphide + acetone
$(C)$ Benzene + toluene
$(D)$ Phenol + aniline

In a mixture of $A$ and $B$ components,the solution shows positive deviation from Raoult's law when:
