What is correct for resonance structure ?
The cannonical forms have no real existence.
The molecule does not exist for a certain fraction of time in one cannonical forms. There is no such equilibrium between the cannonical forms as we have between tautomeric form in tautomerism.
The molecule as such has a single structure which is the resonance hybrid of the cannonical form and which cannot as such be depicted by a single Lewis structure.
