**Resonance Structure Identification Exercise**

**Instruction:**
Please identify the **major** contributing resonance structure (**most significant**) in this case.

**Note:**
- **Major contributor** = the most significant contributor.
- **Minor contributor** = the least significant.
- Insignificant contributors and all other intermediate contributors are not considered.

**Reference:** Review Chapter 2.8.

**Resonance Structures Diagram:**

- The exercise includes a benzene ring with an oxygen atom bonded to it.
- The given structure has resonance arrows indicating the potential movement of electrons.

**Options:**
- **A:** The benzene ring with the oxygen having a positive charge and the ring having a negative charge on one carbon.
- **B:** The benzene ring with a double-bonded oxygen carrying a negative charge.
- **C:** The benzene ring with the oxygen showing a single bond and a negative charge.
- **D:** The benzene ring with the oxygen having both negative and positive charges.
- **E:** The benzene ring with an oxygen double-bonded and a positive charge outside the ring.
- **F:** The benzene ring similar to A, but the charges are more dispersed.
- **G:** The benzene ring with an OH group.
- **H:** The benzene ring with a basic representation of oxygen.

Choose the most significant resonance structure according to established guidelines for evaluating resonance structures in organic chemistry.
