The third line must identify?

• A. All types/categories of CUI contained in the document.
• B. The distribution statement or dissemination controls.
• C. The office making the determination.
• D. The DoD Component name.

Answer: (A)

The third line is where the document flags the CUI categories present. This line tells readers all the types or categories of CUI contained, which is essential for applying the correct handling rules, access restrictions, and dissemination controls. By listing every category up front, anyone who handles the document knows exactly which protections and restrictions apply, so they can comply with the required safeguards for each type of CUI. Other lines in the header serve other purposes—such as indicating dissemination controls, the office or authority that made a determination, or the DoD Component of origin—but the line in question specifically communicates the scope of CUI types present, which guides proper handling throughout the document.
