Which one of the following methods is suitable to generate aromatic compound$(s)$ from linear aliphatic saturated hydrocarbons with at least six carbon atoms?

Identify the product $(C)$ from the given reaction sequence.

Given below are two statements:
Statement $I$: Nitration of benzene involves the following step:
$H-O^+(H)-NO_2 \rightleftharpoons H_2O + NO_2^+$
Statement $II$: Use of Lewis base promotes the electrophilic substitution of benzene.
In the light of the above statements,choose the most appropriate answer from the options given below:

The conversion of benzene to toluene is carried out by .........

The correct order of reactivity in electrophilic substitution reaction of the following compounds is:
