For unclassified material within a CUI document, which marking designates its status?

• A. (U)
• B. (CUI)
• C. No marking
• D. "U" in the header

Answer: (A)

The status is shown with the (U) designation. This parentheses-form mark communicates that, while the document is within the CUI framework, the material itself is Unclassified and should be handled accordingly without elevating its protection level. CUI documents use the overall CUI designation, but the (U) mark specifically communicates unclassified status to readers and handlers. Other options don’t convey this precise status: simply marking CUI communicates category, not the unclassified level, and omitting a mark or placing a non-standard marker would fail to clearly indicate how the content should be treated.
