# Nitrobenzene on reduction using Zinc in alkaline medium results in 'X'. The number of sigma $( \sigma)$ and pi $\pi$ bonds in 'X' is :

$\begin {array} {1 1} (1)\;24 \sigma\: 7 \pi & \quad (2)\;24 \sigma\: 6 \pi \\ (3)\;27 \sigma\: 7 \pi & \quad (4)\;27 \sigma\: 6 \pi \end {array}$

(4) $27 \sigma\: 6 \pi$
