Who is defined as someone authorized to act for or in place of another?

The correct response is C, as the term "agent" specifically refers to an individual who is granted the authority to act on behalf of another party, known as the principal. This role involves carrying out specific tasks, making decisions, and representing the interests of the principal in various situations, such as business dealings or legal matters.

In the context of the law of agency, the agent is legally bound to act in the best interest of the principal, adhering to the duties of loyalty and care. This relationship is foundational in many professional fields, including real estate, where agents represent clients (or principals) in transactions.

Understanding the role of an agent is critical in distinguishing it from other roles such as brokers and clients. While a broker can also act on behalf of clients, the broker typically operates under specific regulations and may not always encompass the broader responsibilities and authority that an agent holds. The client is the individual receiving the services of the agent, and the principal is the party who designates the agent to act on their behalf. Thus, while both clients and principals are integral to the agency relationship, it is the agent who is specifically defined as the one authorized to act for another.
