The correct answer is:
$\mathrm{X}=\mathrm{CH}_3 \mathrm{Cl} / \mathrm{AlCl}_3 \quad \mathrm{Y}=3-$ Methylebenzoic acid
This reaction is not feasible because the $-\mathrm{COOH}$ group interacts with the lewis acid $\mathrm{AlCl}_3$ and forms acylium ion instead of the usual electrophilic substitution at the ring.
