A cleared and properly trained individual responsible for ensuring that they apply the highest possible level of security classification when derivatively classifying information.

• A. Derivative Classifier
• B. Designated Disclosure Authority (DDA)
• C. Designated Government Representative (DGR)
• D. Destruction

Answer: (A)

Derivative classification is the process of assigning a classification to information that stems from already classified material, using the guidance provided by the original classification authorities. The person who performs this work must be cleared and properly trained, and they are responsible for applying the highest level of protection indicated by any source material when deriving the classification. When multiple sources are involved, the final classification should reflect the highest level present to prevent under-protection, and appropriate markings and handling controls must be applied. This role also involves documenting the rationale and ensuring consistency with the source guidance and policy.

Designated Disclosure Authority handles authorized disclosures to outside parties, not the act of deriving classification; Designated Government Representative relates to official government representation in certain matters, and destruction concerns disposal of classified material rather than its classification. The description fits the derivative classifier, the person who ensures information is protected at the correct, highest applicable level.
