In derivatively classifying information, which of the following must be accurate?

• A. The information must be a guess based on other materials
• B. The classification must match the highest level of source information
• C. The classification must be randomly assigned
• D. All unclassified items must remain unclassified

Answer: (B)

The classification of information in derivative classification must align with the highest level of source information available. This principle ensures that when new material is created from previously classified material, the classification level appropriately reflects the sensitivity and handling requirements of that source material.

If the source material is classified at a certain level, then any derivative product based on that material must be classified at the same level or higher if there are additional factors that warrant a higher classification. This approach safeguards national security by preventing the inadvertent release of sensitive information while ensuring that all derived classifications adhere to the original guidelines set forth by the source documents.

The remaining options do not adhere to the principles of derivative classification. Assigning classifications based on guesses is not supported, as accuracy and verifiability are critical. Randomly assigning classifications would undermine the integrity and purpose of the classification system, and unclassified items should not automatically retain an unclassified status if they contain elements derived from classified material.
