The correct response emphasizes the importance of accountability and traceability when handling potentially sensitive materials. When samples are removed from their shipping container, it is essential for the individual unpacking the box to sign off on it. This action ensures that there is a clear record of who handled the samples, which contributes to maintaining proper chain-of-custody protocols.

By signing off, the individual acknowledges receipt and confirms that the samples have been removed from their original container, which is critical for tracking purposes and enhances the integrity of the specimens. This practice aligns with standard protocols in laboratory and medical environments, ensuring that there is documentation reflecting the handling of materials.

In terms of visibility for signs indicating the box's status, while they can support communication about the state of the box (such as "empty" or "contaminated"), they do not replace the need for direct accountability that signing off provides. Therefore, the focus on the immediate signing off aligns best with the key principle of careful handling and documentation of biological samples.
