If a new document contains only unclassified information but references classified events, how should it be marked?

• A. Confidential
• B. Secret
• C. Unclassified
• D. Sensitive

Answer: (C)

When a new document contains only unclassified information but references classified events, it must be marked as unclassified. This is because the classification of a document depends on the information it contains, and in this case, the information within the document is not classified—despite referencing classified events.

The classification system aims to safeguard sensitive information while allowing for the sharing and dissemination of unclassified data. Therefore, marking the document as unclassified appropriately reflects its content and ensures compliance with classification guidance. It informs readers that, while the document discusses classified matters, the information it presents does not warrant classification itself.

In scenarios like this, care should also be taken to prevent any unintended implications that could arise from referencing classified events, but the classification marking must align with the content presented. Thus, marking it as unclassified maintains clarity and adherence to classification protocols.
