In a scenario where a document is derived from multiple sources, which approach to applying downgrading and declassification instructions is correct?

• A. Jo is correct
• B. Both are correct
• C. Neither is correct
• D. Chris is correct

Answer: (D)

When a document draws information from multiple sources, every source’s security requirements must be respected in the final product. The safe and correct approach is to apply the downgrading and declassification instructions in a way that the final document reflects the strictest restriction among all sources. This ensures no information is disclosed beyond what any source permits and keeps provenance and controls intact across the entire derived work. Chris’s approach embodies this principle by adopting the highest applicable restriction and applying it consistently, with justification for the downgrade/declassification. Jo’s approach could leave gaps by not fully incorporating the strictest constraint from all sources, risking unintended disclosures. So, the correct stance is that Chris is correct.
