Consider a solution of $\mathrm{CO}_2(\mathrm{~g})$ dissolved in water in a closed container.

Which one of the following plots correctly represents variation of log (partial pressure of $\mathrm{CO}_2$ in vapour phase above water) $[y$-axis $]$ with $\log$ (mole fraction of $\mathrm{CO}_2$ in water) $[x$-axis $]$ at $25^{\circ} \mathrm{C}$ ?

Choose the correct answer from the options given below :

Given below are two statements :

Statement I : The Henry's law constant $\mathrm{K}_{\mathrm{H}}$ is constant with respect to variations in solution's concentration over the range for which the solution is ideally dilute.

Statement II : $\mathrm{K}_{\mathrm{H}}$ does not differ for the same solute in different solvents.

In the light of the above statements, choose the correct answer from the options given below

The correct order of reactivity of $\mathrm{CH}_3 \mathrm{Br}$ in methanol with the following nucleophiles is
