When a buyer insists the agent breaches their duty to the contract, what is at odds with the agent's duty?

The correct response highlights the obligation of the agent to follow the lawful instructions of the client as part of their duties under a contract. Duty of obedience requires agents to comply with their client’s directives, as long as those directives are lawful and in line with the contractual agreement. When a buyer claims that the agent has breached this duty, it suggests that the agent may not have adhered strictly to the buyer's instructions or desires within the scope of the contract.

In contrast, the other duties listed—such as confidentiality, loyalty, and disclosure—each pertain to different aspects of the agent-client relationship. For instance, the duty of confidentiality requires agents to keep their clients' information private, while the duty of loyalty emphasizes putting the client's interests above all others. The duty of disclosure involves informing clients of all material facts that might affect their decisions. While these duties are essential, they do not directly relate to the obligation to obey the client's instructions. Therefore, when an allegation of breach is made pertaining to the agent's responsibilities under the contract, the duty of obedience is specifically at issue.
