For a solution formed by mixing liquids $$L$$ and $$M,$$ the vapor pressure of $$L$$ plotted against the mole fraction of $$M$$ in solution is shown in the following figure. Here $${X_L}$$ and $${X_M}$$ represent mole fractions of $$L$$ and $$M,$$ respectively, in the solution. The correct statement(s) applicable to this system is (are)

A
The point $$Z$$ represents vapor pressure of pure liquid $$M$$ and Raoult's law is obeyed from $${X_L} = 0$$ to $${X_L} = 1$$
B
The point $$Z$$ represents vapor pressure of pure liquid $$L$$ and Raoult's law is obeyed when $${X_L} \to 1$$
C
The point $$Z$$ represents vapor pressure of pure liquid $$M$$ and Raoult's law is obeyed when $${X_L} \to 0$$
D
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.

The wave function, $${\psi _{n,1,{m_1}}}$$ is a mathematical function whose value depends upon spherical polar coordinates $$\left( {r,\theta ,\phi } \right)$$ of the electron and characterized by the quantum numbers $$n,1$$ and $${m_1}$$. Here $$r$$ is distance from nucleus, $$\theta $$ is colatitude and $$\phi $$ is azimuth. In the mathematical functions given in the table, $$Z$$ is atomic number and $${a_0}$$ is Bohr radius.
