Answer:
D) The Agency Problem
Explanation:
The agency problem refers to a conflict of interests between the principal and his/her agent. Agents have a fiduciary duty to act on the best interest of their principal, but sometimes agents place their own personal interest before the interests of their principal.
in this case, the brokers should act on behalf of their clients to make them earn the largest possible profits, but instead they focus on convincing them about transactions that increased the broker's profit and not the clients'.
