The correct statement regarding the basicity of arylamines is
  1. A
    arylamines are generally more basic than alkalmines because of aryl group
  2. B
    arylamines are generally more basic than alkylmines, because the nitrogen atom in arylamines is sp-hybridised
  3. C
    arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalised by interaction with the aromatic ring π\piπ-electron system
  4. D
    arylamines are generally more basic than alkylamines because the nitrogen lone-pair electrons are not delocalised by interaction with the aromatic ring π\piπ-electron system.

Correct answer: C

In arylamines, lone pair of electrons on nitrogen atom is delocalized over the benzene ring, thus not available for donation so arylamine are less basic than alkylamines.
