The nitration of nitrobenzene with fuming ${\mathrm{HNO}}_3$ will give.

Nitrobenzene on nitration i.e., by using fuming nitric acid, ${\mathrm{HNO}}_3$ forms trinitrobenzene in solid form. The nitro group in nitrobenzene is an electron withdrawing group so when reacted with ${\mathrm{HNO}}_3$, two more nitro groups get attached to the ortho and para position of the benzene ring as because $-{\mathrm{NO}}_2$ group is an ortho-para directing group hence, form 1, 3, 5-trinitrobenzene in short known as TNB.

Therefore, option (A) is correct.
