What is the full syntax for marking special categories and control markings?

The correct answer reflects the established convention for marking special categories and control markings in classified information management. The full syntax is designed to provide clear and specific guidance on the type of classification and any special handling requirements associated with the information.

In this context, the marking begins with the classification level, followed by indications of various special categories that may apply, such as SCI (Sensitive Compartmented Information), and the inclusion of control markings that clarify how the information should be disseminated or handled, including SAP (Special Access Programs), FGI (Foreign Government Information), DISSEM (dissemination restrictions), and other special instructions as needed.

Using this comprehensive syntax ensures that anyone handling classified information understands not only its sensitivity but also the specific requirements for its protection and distribution. This is crucial in maintaining national security and ensuring compliance with relevant regulations.

The other options do not capture the full set of special markings or lack the clarity required for effectively conveying the necessary information about handling procedures and access restrictions. Thus, the choice providing the complete syntax stands out as the most accurate and informative.
