The stability order of these canonical structures is
A.I > II > III
B.III > I > II✓ Correct
C.I > III > II
D.II > III > I
Explanation
II will be least stable, because octet of C+ is incomplete. III will be more stable than I, because in III +ve charges is an N which is less electronegative than O. So, correct order is III >I > II.
