In the reaction :

;
X is

; X is
- A$\mathrm{SiC}$
- B$\mathrm{H}_{2} \mathrm{SO}_{4}$
- C$\mathrm{KMnO}_{4}$
- Correct answerD$\mathrm{Fe}+\mathrm{HCl}$
Solution
The reaction involves the conversion of $\mathrm{NO}_{2}$ to $-\mathrm{NH}_{2}$ group (reduction) which occurs in presence of $\mathrm{Fe} / \mathrm{HCl}$.
Hence, the correct answer is option: 'D'.
