Answer: (C)

Evidence in a persuasive or argumentative essay is what makes your claims credible by grounding them in facts, examples, statistics, and expert opinions. This shows readers why your position is reasonable, not just what you think. Good evidence is relevant to each claim, comes from trustworthy sources, and is explained clearly so readers see how it supports your point. It also helps you address counterarguments by demonstrating why the opposing view doesn’t hold up against solid data or expert insight.

Relying on opinion alone doesn’t persuade because it lacks support. Simply summarizing an opposing viewpoint without evidence doesn’t advance your side, and including unrelated anecdotes can distract and reduce credibility. In short, use solid, clearly connected evidence to back every claim and to build a convincing, well-reasoned argument.
