Prerogative is best defined as:

• A. A privilege or something that one is permitted to do that others aren't
• B. An advantage
• C. A duty
• D. A belief

Answer: (A)

Prerogative is best understood as a privilege or right one is permitted to exercise that others aren’t. It points to an exclusive power or permission tied to a person or office, often granted by authority. That exclusive nature is what makes it stand out: it’s not just any advantage or a general benefit, it’s a special permission reserved for a particular person or group. It’s different from a duty, which is something one must do, and from a belief, which is a conviction or opinion.
