$X = CH_3Cl / AlCl_3$; $Y = 3-\text{Methylbenzoic acid}$

(D) The reaction $X = CH_3Cl / AlCl_3$ is not feasible for benzoic acid because the $-COOH$ group is a strongly deactivating group,which makes the benzene ring unreactive towards electrophilic aromatic substitution. Furthermore,the $-COOH$ group coordinates with the Lewis acid $AlCl_3$ to form a complex,which further deactivates the ring and prevents the Friedel-Crafts alkylation reaction from occurring.
