In this exercise, you are asked to determine the product of a given chemical reaction. The reaction involves a benzene ring reacting with benzyl chloride (\(C_6H_5CH_2Cl\)) in the presence of aluminum chloride (\(AlCl_3\)), a common catalyst for Friedel-Crafts alkylation reactions.

The possible products are labeled as A, B, C, and D, each depicting different structural formations of aromatic compounds:

- **A**: A biphenyl structure with three benzene rings connected in a triangle.
- **B**: The correct product, featuring a trityl cation form where a single benzene ring is attached to a central carbon connected to three benzene rings in a propeller-like shape.
- **C**: A mixed arene structure, with benzene rings in a line with a single connecting bond.
- **D**: A linear chain of benzene rings.

The selected answer was A, which is incorrect. The correct choice is B.

### Explanation of Reaction
In a Friedel-Crafts alkylation, the aluminum chloride acts as a Lewis acid, facilitating the formation of a carbocation from benzyl chloride. The carbocation then reacts with the benzene ring, forming the product B with a distinct trityl cation structure.

This reaction exemplifies the mechanism and product formation for electrophilic aromatic substitution reactions, an important concept in organic chemistry.
