Answer:
same, different is the correct answer.
Explanation:
Resonance structures are a method of explaining bonding in the specific ions and the resonance structures have the same chemical connectivity but different of the electrons are different throughout the structure.
There are certain types of the rule to recognize the resonance structures such as atoms not all show movement, only electrons can move that are present in orbitals and the overall charge of the system remain similar.
Resonance structures explain the delocalization of the electrons in the atom. The structures have the same connectivity, but the difference in the electrons' distribution.
The structure of the compounds has the electrons shared between the atoms that form the stability. The electrons from the bonds are delocalized within the structure to add stability for chemical reactivity.
The delocalization of the electrons in the structure results in the resonance structure.
The resonance structure has the same connectivity between the atoms, but the distribution of the electrons differed. Thus, option D is correct.
