arylamines are generally more basic than alkalmines because of aryl group

arylamines are generally more basic than alkylmines, because the nitrogen atom in arylamines is sp-hybridised

arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring $$\pi $$-electron system

arylamines are generally more basic than alkylamines because the nitrogen lone-pair electrons are not delocalised by interaction with the aromatic ring $$\pi $$-electron system.
