• D. To track who had access to evidence and when, preserving integrity.

Answer: (D)

The purpose of a documented chain of custody is to track who had access to evidence and when, preserving its integrity. By recording every person who collected, handled, or transferred the item, along with times, dates, and locations, you create an auditable trail from the moment the evidence is obtained to its final disposition. This makes it much harder to tamper with or contaminate items without detection and supports reliable reconstruction of events during the investigation. It also helps establish admissibility and credibility of the evidence in reviews or legal proceedings because any gaps or changes in custody can be identified and explained. This approach is not about speeding processing, hiding information, or assigning blame; it is about maintaining the trustworthiness and provenance of evidence throughout the investigative process.
