### Electrophilic Aromatic Substitution (EAS) Reaction Analysis

**Question:**
Which position will an electrophile (E⁺) most likely add in an Electrophilic Aromatic Substitution (EAS) reaction?

**Diagram Explanation:**
The diagram depicts a chlorobenzene molecule with a chlorine atom (Cl) attached to the benzene ring. Four potential positions for electrophilic addition are labeled as A, B, C, and D around the benzene ring. 

- **Position A**: Located ortho to the chlorine substituent.
- **Position B**: Located meta to the chlorine substituent.
- **Position C**: Located para to the chlorine substituent.
- **Position D**: Located meta to the chlorine substituent on the opposite side.

**Concept Explanation:**
In an EAS reaction, electron-withdrawing groups like chlorine typically direct electrophiles to the ortho and para positions (positions A and C). This is due to the resonance and inductive effects, where these positions can stabilize the carbocation intermediate more effectively than the meta positions (B and D).

**Answer:**
The electrophile (E⁺) will most likely add to the ortho (A) or para (C) position relative to the chlorine substituent due to these directing effects.
