Which of the following will not give Hoffmann bromamide reaction?

Identify an aromatic,mixed,$3^{\circ}$ amine from the following.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: Experimental reaction of $CH_{3}Cl$ with aniline and anhydrous $AlCl_{3}$ does not give $o-$ and $p-$methylaniline.
Reason $(R)$: The $-NH_{2}$ group of aniline becomes deactivating because of salt formation with anhydrous $AlCl_{3}$ and hence yields $m-$methylaniline as the product.
In the light of the above statements,choose the most appropriate answer from the options given below.

The reaction of $p$-toluidine with chloroform and alcoholic $KOH$ forms:

What are $X$ and $Y$ in the following reactions?
