Question 77 of 90 in this shift, Chemistry question 17 of 30, Section A.

With respect to the following reaction, consider the given statements : [reaction: aniline (benzene ring with NH2\mathrm{NH_2}) →H2SO4, 288 kHNO3\xrightarrow[\mathrm{H_2SO_4,\ 288\ k}]{\mathrm{HNO_3}} products] (A) o-Nitroaniline and p-nitroaniline are the predominant products. (B) p-Nitroaniline and m-nitroaniline are the predominant products. (C) HNO3\mathrm{HNO_3} acts as an acid. (D) H2SO4\mathrm{H_2SO_4} acts as an acid. Choose the correct option.
