Which of the following statements concerning resonance contributors and resonance hybrids is not correct?
A)The fewer nearly equivalent resonance contributors are in the structure,the greater the resonance energy.
B)A resonance hybrid is more stable than the predicted stability of any of its resonance contributors.
C)The greater the number of relatively stable resonance contributors,the greater the resonance energy.
D)The greater the predicted stability of a resonance contributor,the more it contributes to the resonance hybrid.
E)none of the above

The correct statement is that the greater the number of nearly equivalent resonance contributors, the greater the resonance energy. This is because the delocalization of electrons over multiple atoms increases stability. Therefore, A is the incorrect statement because fewer nearly equivalent resonance contributors result in lower resonance energy.
