Which of the following actions would breach a salesperson's obligation to maintain confidentiality?

The selection of the answer highlights a clear understanding of the obligation a salesperson has to maintain confidentiality in real estate transactions. It emphasizes that providing specific seller information to potential buyers could jeopardize the seller's position during negotiations and violate the duty of confidentiality.

The obligation to maintain confidentiality is fundamental in the real estate profession. Salespersons must protect sensitive information shared by their clients, which can include details such as lowest acceptable price, motivation for selling, and personal comments. When this information is disclosed to prospective buyers without the seller's consent, it could compromise the seller's ability to negotiate effectively, which is why option B accurately encapsulates a breach of this confidentiality obligation.

In contrast, the other actions listed may either involve permissible information sharing, general advertising without compromising confidential details, or situations where the necessity for disclosure might be justified (such as discussions regarding an offer). This distinguishes them from outright breaches of confidentiality. Thus, option B correctly identifies an action that would indeed infringe upon the salesperson's duty to maintain the seller's privacy and confidentiality.
