In chain of custody, what does a link refer to?

• A. The Person Who Takes Possession of Evidence
• B. An Evidence Link Connecting Two Items
• C. The Most Critical Piece of Evidence
• D. The Transport Method Used to Move Evidence

Answer: (A)

The key idea here is how chain of custody tracks custody, not the evidence itself. A link is created each time possession of the evidence changes hands. That link records who takes possession, when, and under what conditions, forming a traceable path of custody. This is what lets you prove the evidence remained under control and unaltered from collection to presentation in court.

So the person who takes possession at a transfer is the element that defines the link—the custodian at that moment—because that’s the point where custody is handed off and the chain is continued. The other options describe different aspects (connecting items, the importance of the evidence itself, or how it was transported) but they don’t capture what a chain-link in custody represents.
