What should be maintained when classifying new information derived from classified sources?

• A. The integrity of the original classification marks
• B. A focus on the final classification assessment only
• C. The original document's length and format
• D. A casual approach to classification

Answer: (A)

Maintaining the integrity of the original classification marks is essential when classifying new information derived from classified sources. This is because the original classification marks indicate the level of sensitivity and the protection required for that information. By preserving these marks when creating derivative classifications, you ensure that the original intent of the classification is respected and maintained. This process helps prevent the inadvertent disclosure of sensitive information.

Additionally, preserving the original classifications aids in maintaining consistency in how information is handled within the classification system, enabling others to understand the provenance of the information and its appropriate level of protection. This practice is foundational in safeguarding national security and sensitive data.
