What are common objections to evidence based on witness statements?

The correct choice accurately identifies key objections related to witness statements based on established legal principles. Hearsay is a primary concern; it refers to a statement made outside of court that is presented to prove the truth of the matter asserted. Such statements are generally inadmissible unless they fall within an exception to the hearsay rule, as the original speaker cannot be cross-examined for credibility.

The best evidence rule mandates that the original document or evidence must be presented when the contents of that document are in dispute. This is crucial in cases involving witness statements that reference specific documents.

Authentication is another important aspect because for testimony or documents to be admissible, they must first be properly authenticated to ensure they are what they claim to be. This relates closely to witness statements, as the credibility and reliability of the statements must be established.

These principles are foundational in evidentiary law and directly pertain to the admissibility of witness statements, providing a comprehensive basis for objections in court.
