$1$-$Chloro$-$4$-$nitrobenzene$,$1$-$Chloro$-$2,4$-$dinitrobenzene$ and $1$-$Chloro$-$2,4,6$-$trinitrobenzene$ are transformed to corresponding phenols with the reagents $X$,$Y$,$Z$ respectively. What are $X$,$Y$,$Z$?

• A
  $X = H_2O$; $Y = NaOH$,$365 \ K$; $Z = NaOH$,$445 \ K$
• B
  $X = (i) \ NaOH, 443 \ K, (ii) \ H^{+}$; $Y = (i) \ NaOH, 368 \ K, (ii) \ H^{+}$; $Z = \text{Warm } H_2O$
• C
  $X = (i) \ NaOH, 625 \ K, (ii) \ H^{+}$; $Y = (i) \ NaOH, 440 \ K, (ii) \ H^{+}$; $Z = H_2O / H^{+}$
• D
  $X = NaOH, 625 \ K$; $Y = H_2O$; $Z = NaOH, 440 \ K$
