(B) According to the Bronsted-Lowry theory,an acid is a proton donor and a base is a proton acceptor. In the nitrating mixture,conc. $H_2SO_4$ acts as a strong acid and donates a proton to conc. $HNO_3$. The reaction is: $HNO_3 + H_2SO_4 \rightarrow H_2NO_3^+ + HSO_4^-$. Here,$HNO_3$ accepts a proton from $H_2SO_4$,therefore $HNO_3$ acts as a base. Subsequently,$H_2NO_3^+$ decomposes to form the electrophile $NO_2^+$: $H_2NO_3^+ \rightarrow NO_2^+ + H_2O$.

Nitrobenzene can be prepared from benzene by using a mixture of conc. $HNO_3$ and conc. $H_2SO_4$. In the mixture,nitric acid acts as a/an
