What can be offered in court to prove the truth or falsity of a fact at issue?

To establish the truth or falsity of a fact at issue in court, evidence is critical. Evidence encompasses a broad range of materials and information presented during legal proceedings that can help the court make informed decisions. This could include physical objects, documents, witness statements, or expert opinions that support or dispute the claims being made.

While affidavits and witness testimony are indeed forms of evidence, they are specific types within the broader category of evidence. Legal arguments are crucial in interpreting the law and applying it to the facts but do not directly prove the truth or falsity of those facts. Therefore, the correct choice emphasizes the overall category that includes all means of verifying information relevant to a case.
