What can physical evidence produce in court?

Physical evidence plays a crucial role in court proceedings as it can provide tangible proof that supports a case. The correct option highlights that physical evidence can indeed be part of a dual item of evidence, which includes both expert testimony and the exhibit itself.

When physical evidence, such as fingerprints, DNA, or weapons, is presented in court, it often requires an expert to interpret or explain its significance. This expert testimony adds credibility and context, helping the court understand not just what the evidence is but how it relates to the case. The exhibit, which is the actual item or substance that has been collected at a crime scene, serves as visual support of the expert's analysis.

In contrast, other options limit the role of physical evidence. Witness testimonies alone do not encompass the full value of physical evidence, nor does it exclusively rest on law enforcement documentation or just witness statements. Physical evidence, when combined with expert insight, provides a more comprehensive basis for establishing facts and supporting arguments in court.
