Step 1

Resonance is the movement of electrons or pi-bonds in a molecule. It is the method that describes the delocalization of electrons within molecules. It compares and contrasts two or more possible Lewis structures that can represent a particular molecule.

A molecule or ion with such delocalized electrons is represented by two or more contributing structures (also called resonance structures or possible Lewis structures)

Step 2

In the given question, structure I, II and IV undergoes resonance as shown below forming one more possible Lewis structure except structure III, which donot undergo resonance and therefore has no other possible Lewis structure.

Structure I :
