Answer:
Fiduciary.
Step-by-step explanation:
A fiduciary is known as a person or organization that acts on behalf of another person or persons to manage assets. Essentially, a fiduciary owes to that other entity the duties of good faith and trust. The highest legal duty of one party to another, being a fiduciary requires being bound ethically to act in the other's best interests.
A fiduciary might also be responsible for general well-being, but often the task involves finances, managing the assets of another person, or of a group of people, for example. Money managers, financial advisors, bankers, accountants, executors, board members, and corporate officers all have fiduciary responsibility.
