Which scenario exemplifies a conflict of fiduciary duties?

A conflict of fiduciary duties arises when an agent faces competing obligations that may compromise their ability to act in the best interests of their client. In this scenario, when Nikki's seller client instructs her not to present low offers, it creates a conflict in her responsibilities as a fiduciary. Nikki has a legal and ethical obligation to present all offers to her client, regardless of their perceived value. By following her client's instruction to withhold specific offers, Nikki would be violating her duty of loyalty and full disclosure, which could lead to potential harm or disadvantage for her client in the negotiations.

Presenting all offers allows the seller to make an informed decision, and not doing so jeopardizes both Nikki's fiduciary duties and the client's best interests. Thus, this scenario exemplifies a conflict of fiduciary duties more clearly than the other choices, which do not directly involve compromising responsibilities or obligations to clients.
