Which data classification includes blueprints for weapons or other information that could gravely damage national security if disclosed?

• A. Confidential Data (Military/Government)
• B. Top Secret Data (Military/Government)
• C. Secret Data (Military/Government)
• D. Unclassified Data

Answer: (C)

Data classifications are about how sensitive information is and how tightly it must be protected. When disclosure could cause grave damage to national security, the material is categorized as Secret Data. This level is intended for highly sensitive information—like weapon blueprints or other critical national security details—that, if exposed, would lead to serious harm. It requires strong access controls and handling procedures, but not the extreme protections reserved for the highest level.

The other levels fit less severe scenarios: Unclassified is information that doesn’t require protective controls, or only minimal ones; Confidential would cause damage but not to the level of grave harm; Top Secret is reserved for information whose disclosure could cause exceptionally grave damage, which is more sensitive than Secret data.
