(Assume : Densities of the solutions $A$ and $B$ are the same as that of water and the soluble salts dissociate completely.)
Use: Molal elevation constant (Ebullioscopic Constant), $K _{ b }=0.5 K kg mol ^{-1}$; Boiling point of pure water as $100^{\circ} C$.)
($1$) The value of $x$ is
($2$) The value of $|y|$ is

$[A]$ 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 $x_{L}=1$
