Final answer:
The best answer regarding the law of agency is D.
Step-by-step explanation:
The best answer regarding the law of agency is D. Where an agent has actual, apparent, or an agency relationship formed by ratification, the agent is bound to the terms of an agreement entered into.
This means that if an agent acts on behalf of a principal and enters into an agreement, they are legally obligated to follow the terms of that agreement.
For example, if an agent signs a contract for a principal without the principal's authorization, the agent can still be bound by that contract if it falls under one of the categories mentioned.
