Step-by-step explanation:
Ely, as a real estate broker who represents the seller in a transaction, owes fiduciary duties to the seller. These duties include loyalty, confidentiality, obedience, accounting, and disclosure, among others. It is part of Ely's professional responsibility to act in the best interests of the seller and to provide a standard of care that includes promoting the seller's best interests above her own. While intermediary duties pertain to a broker facilitating a transaction as a neutral party, and common duties could refer to general business practices, it is the fiduciary duties that are most specific and obligatory to the seller in the context of a broker-client relationship.
