Given below are two statements :

Given : Molar mass of $\mathrm{C}, \mathrm{H}, \mathrm{O}, \mathrm{Cl}$ are $12,1,16$ and $35.5 \mathrm{~g} \mathrm{~mol}^{-1}$, respectively

Statement I : In $30 \%(\mathrm{w} / \mathrm{w})$ solution of methanol in $\mathrm{CCl}_4($ at T K$)$, the mole fraction of $\mathrm{CCl}_4$ is equal to 0.33 .

Statement II : Mixture of methanol and $\mathrm{CCl}_4$ shows positive deviation from Raoult's law. In the light of the above statements, choose the correct answer from the options given below :
