Extrinsic evidence refers to information that is external to the main document or evidence being considered. In this context, it is used to prove a detached fact, meaning it helps to establish a point or fact that is not encompassed within the original document itself. This type of evidence is often important in legal and survey contexts, as it can clarify, support, or contradict the details presented in a primary source.

The focus is on how this evidence can provide insight or understanding beyond what is contained within the original material, acting as an additional layer of proof. Although extrinsic evidence can come from various sources, such as witness testimonies or physical evidence, its primary characteristic is its role in supporting facts that exist outside the scope of the original documentation.

Other options, while potentially relevant in different contexts, do not capture the essence of extrinsic evidence. For example, evidence provided by a witness pertains more closely to testimonial evidence rather than the standalone verification of detached facts. Additionally, original documentation itself would not classify as extrinsic since it is the primary source. Finally, the notion of indisputable evidence applies to absolute proof but is not a specific characteristic of what is deemed extrinsic.
