Chlorobenzene ( X ) when reacted with reagent ' \(A\) ' gets converted to phenol (Y). The major product obtained from nitration of \(X\) gets converted to p-nitrophenol \((\mathrm{Z})\) by reaction with reagent B . What are A and B respectively?

1. A \(\begin{aligned} & \mathrm{A}=\text { = (i) } \mathrm{NaOH}, 623 \mathrm{~K}, 300 \mathrm{~atm} \text { (ii) } \mathrm{H}^{+} ; \\ & \mathrm{B}=\text { (i) } \mathrm{NaOH}, 443 \mathrm{~K} \text { (ii) } \mathrm{H}^{+}\end{aligned}\)
2. B \(\begin{aligned} & \mathrm{A}=\text { (i) } \mathrm{NaOH}, 443 \mathrm{~K} \text { (ii) } \mathrm{H}^{+} ; \\ & \mathrm{B}=\mathrm{H}_2 \mathrm{O}, \Delta\end{aligned}\)
3. C \(\begin{aligned} & \mathrm{A}=\text { (i) } \mathrm{NaOH}, 323 \mathrm{~K} \text { (ii) } \mathrm{H}^{+}: \\ & \mathrm{B}=\text { (i) } \mathrm{NaOH}, 443 \mathrm{~K} \text { (ii) } \mathrm{H}^{+}\end{aligned}\)
4. D \(\begin{aligned} & \mathrm{A}=\text { (i) } \mathrm{NaOH}, 623 \mathrm{~K}, 300 \mathrm{~atm} \text { (ii) } \mathrm{H}^{+} ; \\ & \mathrm{B}=\mathrm{H}_2 \mathrm{O}, \Delta\end{aligned}\)
