Final answer:
The correct option is B). In California, Transaction brokerage is not permitted, whereas Dual agency, Single agency, and Representing a buyer are allowed with appropriate consent and disclosures.
Step-by-step explanation:
The type of agency relationship that is not permitted in California is B) Transaction brokerage. In California, the practice of transaction brokerage—where a real estate agent or broker facilitates a transaction without representing either party—is not allowed. The three types of agency relationships that are allowed in California are Dual agency, Single agency, and Representing a buyer. Dual agency refers to an agent representing both the buyer and the seller in the same transaction, which is legal in California if all parties provide informed consent. Single agency means representing either the buyer or the seller exclusively. Representing a buyer indicates that the agent is acting solely on behalf of the buyer.
