What best describes the role of evidence in a case of fact?

The role of evidence in a case of fact is fundamentally about establishing the truth or falsehood of claims being made. In legal contexts, for instance, evidence is used to substantiate assertions regarding what actually occurred in relation to the case. This can encompass a variety of forms, such as documents, witness testimonies, physical evidence, and expert opinions. These pieces of evidence work together to create a coherent argument that either confirms or disputes the facts at hand.

By verifying the truth or falsehood, evidence enables all parties involved in a case—judges, juries, and attorneys—to make informed decisions based on objective data rather than mere assertions or beliefs. This objective foundation is crucial, as it leads to more reliable and just outcomes in conflict resolutions, making it clear why this option is the accurate description of evidence's role.
