The doctrine of respondeat superior is most often applied in situations involving:

A) torts of the agent.
B) negligence of the principal.
C) contracts negotiated by the agent.
D) crimes committed by the agent.

The doctrine of respondeat superior applies primarily in situations involving torts committed by an agent (e.g., an employee) while acting within the scope of their employment. This legal principle holds the employer (principal) liable for the actions of their employees.
