Rhetoric is best defined as:

• A. Language used to persuade. There are three types; logos, pathos, and ethos.
• B. A topic; the subject of a discourse.
• C. A person, place, or object that stands for something beyond itself.
• D. The protagonist of a tragedy.

Answer: (A)

Rhetoric is the art of influencing an audience through language. The strongest definition here ties rhetoric to persuasion by specifying language used to persuade and by naming the classical appeals—logos, ethos, and pathos—that speakers deploy to convince: logical argument, credibility, and emotional appeal. This focuses on how rhetoric works to sway listeners, not just what is being discussed or who is involved.

Why this fits best: rhetoric isn’t simply the topic of a discourse, nor a symbol, nor a person in a story. If you said rhetoric was just the subject, you’d be labeling what’s being talked about rather than how it’s being argued. If you called it a symbol, you’d be describing a literary device that stands for something else. If you called it the protagonist, you’d be naming a character in a tragedy. The option that emphasizes persuasive language and the three appeals captures the practical purpose and method of rhetoric.
