The correct option is C
(a) $P h - N_{2} C l + H_{2} O Δ - \to P h - O H + N_{2} + H C l$

(b) $P h - S O_{3} H F u s e d N a O H - ------- \to P h - O^{-} N a^{+} H^{+} - - \to P h - O H$

(c) In normal conditions nucleophilic aromatic substitution does not take place.

(d) $C u m e n e O_{2} - \to P h - C (C H_{3})_{2} (O - O - H) Cumene hydroperoxide H_{2} O / H^{+} - ---- \to P h - O H + C H_{3} C O C H_{3}$
