The correct answer is: $\mathrm{CH}_{3} \mathrm{NH}_{2}$
Basic nature of amine is due to the presence of lone pair of electrons on nitrogen atom which is available for the bond formation with Lewis acid. Due to $+I$ effect of $-\mathrm{CH}_{3}$ group, $\mathrm{CH}_{3} \mathrm{NH}_{2}$ is the strongest base.
