Answer:
a. Doctors pursuing their own interests rather than the interests of their patients
Step-by-step explanation:
A principal is an individual or a group that entrusts a certain responsibilities to someone else (known as the agent) in an entity . The agent therefore has superior information than the principal and therefore the former makes decisions on behalf of the latter. A conflict of interest can occur when the agent pursues his own interests for personal gains and ignores the responsibility he was hired to do hence creating Principal-Agent problem. Among these choices, doctors pursuing their own interests rather than the interests of their patients will lead to principal agent problem.
