Examine the following two structures for the anilinium ion and choose the correct statement from the ones gives below:
A. `II` is not an acceptable canonical structure because carbonium ions are less stable than ammonium ions.
B. `II` is not an acceptable canonical structure because it is non-aromatic.
C. `II` is not acceptable canonical structure because the nitrogen has `10` valence electrons.
D. `II` is an acceptable canonical sturcture.
