Quizplus · Accepted Answer

In pair C, the formal charges are different on each structure, indicating that they are not resonance structures of the same species. Therefore, it is not a pair of resonance structures. The other pairs (A and B) have the same formal charges on each structure and thus are resonance structures. The answer cannot be D, as stated in the answer choices, as C is not a resonance structure.
