Give the possible structure of $\mathrm{X}$ in the following reaction :
$$
\mathrm{C}_{6} \mathrm{H}_{6}+\mathrm{D}_{2} \mathrm{SO}_{4} \stackrel{\mathrm{D}_{2} \mathrm{O}}{\longrightarrow} \mathrm{X}
$$
- A

- B

- C

- Correct answerD

Solution
$\mathrm{D}_{2} \mathrm{SO}_{4}$ transfers $\mathrm{D}^{+}$, an electrophile, to form hexadeuterobenzene.
Hence, the correct answer is option: 'D'.
