Among the haloarenes (I-IV) shown below, the correct order of reactivity for the substitution reaction with NaOH is

• A

  $\mathrm{IV}\gt\mathrm{I} \approx \mathrm{III}\gt\mathrm{II}$.
• B

  $\mathrm{I}\gt\mathrm{IV}\gt\mathrm{III}\gt\mathrm{II}$.
• C

  II $\gt$ III $\gt$ IV $\gt$ I.
• Correct answer
  D

  $\mathrm{II}\gt\mathrm{III} \approx \mathrm{I}\gt\mathrm{IV}$.

Hence, the correct answer is option: 'D'.
