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.
