Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Experimental reaction of $\mathrm{CH}_{3} \mathrm{Cl}$ with aniline and anhydrous $\mathrm{AlCl}_{3}$ does not give $o$ and $p$-methylaniline.
Reason (R): The $-\mathrm{NH}_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $\mathrm{AlCl}_{3}$ and hence yields $m$-methyl aniline as the product.
