Impeachment evidence is used to challenge a witness’s believability. It doesn’t by itself prove the facts a witness is saying, but it affects how much weight the jury should give that testimony by casting doubt on the witness’s honesty or reliability. Examples include prior inconsistent statements, evidence of bias, or a reputation for untruthfulness. That’s why the best choice is the one that states the purpose as impeaching the credibility of the witness—because impeachment aims to undermine credibility to influence how much the testimony is trusted. The other ideas described either imply determining credibility outright, suggest something about admissibility in a way that’s not accurate, or miss the specific purpose of impeachment.
