Q. Nitration of aniline in strong acidic medium also gives m-nitroaniline because
A) In absence of substituents nitro group always goes to m-position.
B) In electrophilic substitution reactions amino group is meta directive.
C) In spite of substituents nitro group always goes to only m-position.
D) In acidic (strong) medium aniline is present as anilinium ion.
