$[A]$ Attractive intermolecular interactions between $L-L$ in pure liquid $L$ and $M-M$ in pure liquid $M$ are stronger than those between $L-M$ when mixed in solution

$[B]$ The point $Z$ represents vapour pressure of pure liquid $M$ and Raoult's law is obeyed when $x_{L} \rightarrow 0$

$[C]$ The point $Z$ represents vapour pressure of pure liquid $L$ and Raoult's law is obeyed when $x_{\mathrm{L}} \rightarrow 1$

$[D]$ The point $Z$ represents vapour pressure of pure liquid $M$ and Raoult's law is obeyed from $x_{L}=0$ to $x_{L}=1$

(Given : $\Delta_{\mathrm{r}} \mathrm{H}_{298 \mathrm{~K}}^{\circ}=-54.07 \mathrm{~kJ} \mathrm{~mol}^{-1}, \Delta_{\mathrm{I}} \mathrm{S}_{298 \mathrm{~K}}^{\circ}=10 \mathrm{JK}^{-1} \mathrm{~mol}^{-1}$ and $\mathrm{R}=8.314 \mathrm{JK}^{-1} \mathrm{~mol}^{-1} ; 2.303 \times 8.314 \times 298=5705$ )

$[Y]$ is
