The correct statement regarding the basicity of arylamines is:

Arylamines are generally more basic than alkylamines, because the nitrogen atom in arylamines is sp-hybridized.

Arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring $\displaystyle \pi$ electron system.

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

Arylamines are generally more basic than alkylamines because of aryl group.
