The correct statement regarding the basicity of arylamines is
(1) Arylamines are generally more basic than alkylamines because the nitrogen lone-pair electrons are not delocalized by interaction with the aromatic ring p-electron system.
(2) Arylamines are generally more basic than alkylamines because of aryl group.
(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 p-electron system.
