Final answer:
A person in a position of trust and confidence is known as a/an fiduciary (option C).
Step-by-step explanation:
A person in a position of trust and confidence is known as a fiduciary. This is a legal term that describes a relationship wherein one party, known as the fiduciary, acts on behalf of another party, known as the principal, and is bound to act in the best interests of the principal. This relationship is often found in various business, financial, and legal scenarios. Positions that typically involve a fiduciary duty include trustees of a trust, guardians, executors, or corporate directors.
On the other hand, a partner or an associate typically refers to someone who shares a business relationship on more equal terms rather than a responsibility to act in the other's best interest. A subordinate refers to someone who works under the authority of someone else and does not have a fiduciary responsibility to their superior.
