The reaction of compound $\mathbf{P}$ with $CH_3 MgBr$ (excess) in $\left(C_2 \mathrm{H}_5\right)_2 O$ followed by addition of $H_2 O$ gives $Q$. The compound $Q$ on treatment with $H_2 SO_4$ at $0^{\circ} C$ gives $R$. The reaction of $R$ with $CH_3 COC1$ in the presence of anhydrous $AlCl_3$ in $CH_2 Cl_2$ followed by treatment with $H_2 O$ produces compound $S$ [ $Et$ in compound $P$ is ethyl group]

($2$) The reactions, $Q$ to $R$ and $R$ to $S$, are
$[A]$ Dehydration and Friedel-Crafts acylation
$[B]$ Aromatic sulfonation and Friedel-Crafts acylation
$[C]$ Friedel-Crafts alkylation, dehydration and Friedel-Crafts acylation
$[D]$ Friedel-Crafts alkylation and Friedel-Crafts acylation
