Answer:
d. The agent has not violated any duties, because she is not performing real estate services for the buyers
Step-by-step explanation:
Here, at the open house, the agent, without proper introduction and without explaining that she represents the seller, started giving advice to a prospective buyer regarding the amount to offer for the house. By offering advice to the buyer and not disclosing who she represents, the agent is now acting as an undisclosed dual agent, also she has breached the loyalty duties to both parties. The agent is also not acting in accordance with her agency status.
Therefore the incorrect option is option D.) The agent has not violated any duties, because she is not performing real estate services for the buyers
