Resonance structures of aniline are shown below



Considering the above structures, it can be concluded that

• A

  60 \% of the molecules of aniline exist as structures II, III and IV.
• B

  In aniline, the N -atom carries one unit positive charge.
• Correct answer
  C

  Aniline has dipole moment with the N -atom as the positive end.
• D

  The meta position of aniline is electron deficient in comparison to benzene.

Hence, the correct answer is option: 'C'.
