(B) In the nitration of benzene using a mixture of concentrated $HNO_3$ and concentrated $H_2SO_4$,the sulfuric acid acts as a strong acid and protonates the nitric acid. The reaction is as follows: $HNO_3 + H_2SO_4$ $\rightarrow H_2NO_3^+ + HSO_4^-$ $\rightarrow H_2O + NO_2^+ + HSO_4^-$. In this process,$HNO_3$ accepts a proton $(H^+)$ from $H_2SO_4$,and according to the Brønsted-Lowry theory,a substance that accepts a proton acts as a base.

During the mixed acid nitration of benzene,concentrated $HNO_3$ behaves like:
