The answer for the Lewis structure for this question says that there are more resonance structures available, but what would be the best resonance structure? And do different resonance structures affect the structure of the molecule?

We usually say the "best" resonance structure is the one with the lowest formal charge on each atom (this means it has the most stability). Resonance structures only affect the structure of a molecule if different structures have different numbers of regions of electron density.
