Final answer:
The broker has no authority to withhold offers from the seller, as all offers must be presented to allow the seller to make an informed decision. Withholding information violates the broker's fiduciary duty to act in the best interest of their client.
Step-by-step explanation:
In the scenario presented, the broker has withheld a higher offer from the seller after already presenting an earlier, lower offer. According to professional ethics and legal obligations in real estate, it is the duty of the broker to present all offers received to the seller to allow them to make an informed decision. Any action to withhold such information undermines the seller's ability to act in their best interest.
Therefore, the correct answer is: The broker has no authority to withhold offers from the seller. All offers on a property must be communicated to the seller unless the seller has specifically instructed otherwise in writing. By not doing so, the broker risks violating the fiduciary duty owed to the seller. Real estate agents are legally obligated to act in the best interests of their clients, which includes providing complete and accurate information relevant to any transaction.
