The nitration of aniline in a strong acidic medium results in the formation of m-nitroaniline because:

1. In spite of substituents nitro group always goes to only m-position
2. In electrophilic substitution reactions amino group is meta directive
3. In absence of substituents nitro group always goes to only m-position
4. In an acidic (strong) medium aniline is present as anilinium ion
