A)  \[24\sigma ,\,7\pi \]          

B)  \[24\sigma ,\,6\pi \]

C)  \[27\sigma ,\,7\pi \]

D)  \[27\sigma ,\,6\pi \]

Correct Answer: D

Solution :

Nitrobenzene on reduction using zinc in alkaline medium gives hydrazobenzene.                 Hydrazobenzene (X) contains \[27\sigma \] and \[6\pi \]bonds.
