The appropriate selection in this context is grounded in the concept that evidence must be handled in a manner that preserves its integrity to be considered reliable. When John submits evidence that is free from any tampering, it indicates that the evidence has maintained its original state, thus enhancing its trustworthiness.

Reliability in forensic contexts implies that the evidence can be depended upon to accurately represent what it purports to establish. This is crucial because any alterations or tampering could undermine the validity of the evidence, potentially leading to misinterpretations and false conclusions.

Understanding the other options provides additional clarity. Authenticity addresses whether the evidence is what it claims to be but does not necessarily speak to whether it has been preserved in an unaltered state. Admissibility refers to whether evidence can be legally introduced in a court of law, which involves several factors beyond just the integrity of the evidence itself. Corroborative evidence supports or confirms other evidence but does not relate to the handling or presentation of the evidence in question.

In this case, the focus on the evidence being untampered leads directly to its reliability as a trustworthy piece of information in the investigation or legal process.
