    Identify\[X\]\[{{C}_{6}}{{H}_{6}}\xrightarrow[reflux]{HN{{O}_{3}}/{{H}_{2}}S{{O}_{4}}}\]Intermediate\[\xrightarrow[heat]{Sn/HCl}X\]

A)  

B)  

C)     

D)  

Correct Answer: A

Solution :

                Nitration of benzene with cone.\[HN{{O}_{3}}\]and cone\[{{H}_{2}}S{{O}_{4}}\]will stop at the nitrobenzene stage because\[-N{{O}_{2}}\]group is deactivating and hence fuming\[HN{{O}_{3}}\]will be required for further nitration.
