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

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

The correct statement regarding the basicity of arylamines is:

1. Arylamines are generally more basic than alkylamines because the lone-pair electrons of nitrogen are not delocalized by interaction with the aromatic ring π-electron system.
2. Arylamines are generally more basic than alkylamines because of the aryl group +I effect.
3. Arylamines are generally more basic than alkylamines because the nitrogen atom in arylamines is sp-hybridized.
4. Arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring π-electron system.
