Which of the following is NOT a persuasive technique?

• A. Appeals to emotion.
• B. Appeals to reason.
• C. Random guessing.
• D. Credibility (ethos).

Answer: (C)

Understanding persuasive techniques is about how a speaker tries to convince an audience. Appeals to emotion use feelings to motivate belief or action; appeals to reason rely on facts, logic, and evidence to support a claim; credibility (ethos) rests on the speaker’s trustworthiness or authority. Random guessing isn’t a strategy meant to persuade. It doesn’t aim to move someone through emotion, logic, or credibility, and it doesn’t present a deliberate argument. So it isn’t a persuasive technique, unlike the other options that are established ways to influence an audience.
