In resonance structures, only the position of electrons is different, but the position of atoms remains the same. In option C, the position of the atoms is different, so it is not a resonance structure of the same species. Options A and B are resonance structures because they have the same position of atoms and electrons, just different electron configurations. Option D cannot be correct because option C is not a resonance structure. Option E cannot be correct because options A and B are resonance structures.
