The correct statement regarding the basicity of arylamines is
A
arylamines are generally more basic than alkalmines because of aryl group
B
arylamines are generally more basic than alkylmines, because the nitrogen atom in arylamines is sp-hybridised
C
arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring $$\pi $$-electron system
D
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.
