Agents have a duty to keep and render an accounting of money, documents, and property that they have received or paid out on behalf of the

A brokerage refers to a firm or individual that facilitates transactions between buyers and sellers, typically in real estate or financial markets. While agents may work for a brokerage, the duty to account for money and property specifically pertains to the principal, not the brokerage itself. The brokerage is not the entity on whose behalf the agent acts in the context of this duty.

The term "customer" generally refers to an individual who purchases goods or services, but in the context of agency, it does not denote the party for whom the agent acts. An agent’s reporting obligations are directed towards the principal, who is the individual or entity that granted the authority to act. Therefore, the duty of accounting is not owed to customers in the same capacity.

While agents do operate under a fiduciary duty, the term "fiduciary" itself does not specify the party to whom the duty is owed. A fiduciary is a role characterized by trust and responsibility, but the accounting duty must be rendered specifically to the principal, who is the party that the agent represents. Thus, this choice is too broad and does not accurately identify the correct answer.
