Final answer:
An exclusive agency is a type of agency relationship where the agent is hired to perform a specific duty on behalf of the principal.
Step-by-step explanation:
An agent hired to perform a specific duty is best described as an exclusive agency.
An exclusive agency is a type of agency relationship where the principal grants exclusive rights to the agent to perform specific tasks on their behalf. The agent is specifically hired for a particular purpose or duty and is given limited authority to act on behalf of the principal.
For example, a real estate agent who is exclusively hired by a homeowner to sell their property is an example of an exclusive agency. The agent is authorized to perform the specific duty of selling the property, but does not have general authority to act on behalf of the homeowner in other matters.
