$x$ is

The electrophilic aromatic substitution proceeds through a

The product $(A)$ is:

Identify the correct statements for a ring system to exhibit aromaticity.
$(i)$ It must not be planar.
$(ii)$ It must possess $(4n+2) \pi$-electrons.
$(iii)$ It must be planar.
$(iv)$ It must possess $4n \pi$-electrons.
The correct answer is

In the reaction $C_6H_5CH_3$ $\xrightarrow{\text{Oxidation}} A$ $\xrightarrow{NaOH} B$ $\xrightarrow{\text{Sodalime}} C$. Then $C$ is
