The correct statement regarding the basicity of arylamines is

• A
  arylamines are generally more basic than alkylamines because of aryl group
• B
  arylamines are generally more basic than alkylamines,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.
