Question
The image presents a multiple-choice chemistry question addressing the determination of the major organic product of a given reaction. The reaction involves reactants and expected products as follows:

### Reaction:

**Reactants:**
- A benzene ring with two carboxylic acid groups (COOH) at the para position is reacted with ethylene glycol (HOCH2CH2OH).

**Conditions:**
- The reaction takes place in an acidic environment, indicated by the presence of H+.

### Possible Products:

**I.**
- A compound where the benzene ring has a para dicarboxylic acid with an ether linkage (CH2CH2 group) between two benzene rings.

**II.**
- A compound with a single ether linkage (CH2CH2O) connecting one of the benzene rings to an additional benzene ring, with a single carboxylic acid group.

**III.**
- A compound where two benzene rings are linked by a glycol moiety, forming a cyclic structure with two ester groups. Both benzene rings have two functional groups, one being an ether and the other an ester linkage.

**IV.**
- A compound where each of the two benzene rings is connected by an ester linkage, forming an ester bridge dissociated by two different oxygen atoms bonded to each aromatic ring.

**V.**
- A structure featuring a benzene ring with a ketone group (CO) directly bonded to both the aromatic compounds and an ether linkage bound to another benzene ring.

### Answer Choices:

- **A) I**
- **B) II**
- **C) III**
- **D) IV**

The question involves determining the correct structural representation that correlates with the expected major organic product formed under the described reaction conditions. The reaction mechanics likely entail esterification, which might suggest the structures involving ester bonds as potential candidates for the correct answer.
