b)

c)

Step-by-step solution

Resonance definition

Resonance is nothing but the delocalization of electrons within a molecule.

There are certain rules to draw the resonating structure:

1. In a resonating structure, only electrons are move while the position of atoms remains the same.

2. Only pi electrons and lone pair of electrons move.

Resonance of compound (a)

In the following resonating structure lone pair of electrons on nitrogen is delocalize which results in the formation following structure;
