What is the product $X$ in the following Wurtz-Fittig reaction?

Which chloroderivative of benzene among the following would undergo hydrolysis most readily with aqueous $NaOH$ to furnish the corresponding hydroxy derivative?

The reaction of compound $P$ with $CH_3MgBr$ (excess) in $(C_2H_5)_2O$ followed by addition of $H_2O$ gives $Q$. The compound $Q$ on treatment with $H_2SO_4$ at $0^{\circ}C$ gives $R$. The reaction of $R$ with $CH_3COCl$ in the presence of anhydrous $AlCl_3$ in $CH_2Cl_2$ followed by treatment with $H_2O$ produces compound $S$ [$Et$ in compound $P$ is ethyl group].
$(1)$ The product $S$ is
$(2)$ 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

Given the answer question $(1)$ and $(2)$

The above reaction requires which of the following reaction conditions?

Which of the following is not used in the Friedel-Crafts reaction?

The azo-dye $(Y)$ formed in the following reactions is: $\text{Sulphanilic acid} + NaNO_2 + CH_3COOH \rightarrow X$; $X + \text{1-naphthylamine} \rightarrow Y$. Identify $Y$.
