15. An individual broker may NOT be designated to work for both a seller and a buyer in the same transaction as

Answer: B

Explanation:

An individual broker may NOT be designated to work for both a seller and a buyer in the same transaction as an agent for both.

In real estate transactions, a broker cannot serve as an agent for both parties due to the inherent conflict of interest this creates. This restriction ensures that the interests of both the seller and buyer are adequately represented without bias.

A) A transaction broker for both

A transaction broker acts as a neutral facilitator for both parties without representing either as a client. This role does not create a conflict of interest, allowing a broker to work with both the seller and the buyer simultaneously, making this option incorrect regarding the prohibition of dual agency.

B) An agent for both

An agent must represent the interests of one party exclusively, which is why a broker may not be designated as an agent for both the seller and the buyer in the same transaction. This position inherently creates a conflict of interest, justifying the need for clear representation.

C) A single agent for the seller, treating the buyer as a customer

This option describes a situation where the broker represents the seller, thus prioritizing the seller's interests while treating the buyer as a customer. While this is permissible, it does not address the scenario of representing both parties as agents, making it an incorrect choice in the context of the question.

D) A single agent for the buyer, treating the seller as a customer

Similar to option C, this choice allows for the broker to represent one party (the buyer) while treating the other (the seller) as a customer. This arrangement does not involve representing both as agents, thus this option is also incorrect in relation to the prohibition highlighted in the question.

Conclusion

The correct answer, B, highlights the prohibition against a broker acting as an agent for both a seller and a buyer in the same transaction due to the conflict of interest that arises. Options A, C, and D do not violate this principle, as they either allow for neutral facilitation or clear representation of one party only, thereby reinforcing why B is the definitive answer in this context.
