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.
