Question

Which of the following statements regarding resonance contributors and resonance hybrids is correct?

A. The greater the predicted stability of a resonance contributor, the less it contributes to the resonance hybrid.

B. The resonance hybrid is more stable than the predicted stability of any of its resonance contributors because it is the sum of all stable resonance contributors.

C. The fewer nearly equivalent resonance contributors are in the structure, the greater the resonance energy.

D. The resonance hybrid will show all pi bonds and locations of all full charges.

I know the correct answer is B. I am having trouble understanding resonance could you please explain why A,C, and D is wrong and why B is correct.
