Which statement lists the four levels of security?

• A. Top Secret, Secret, Confidential, Classified
• B. Top Secret, Secret, Confidential, Unclassified
• C. Top Secret, Secret, Restricted, Unclassified
• D. Secret, Confidential, Unclassified, Unclassified

Answer: (B)

Understanding security classifications is about the standard levels used to mark information by sensitivity. The four commonly used levels are Top Secret, Secret, Confidential, and Unclassified, arranged from highest protection to least. This ordering matters because it matches the handling rules and safeguards to how damaging disclosure could be, with Top Secret requiring the most stringent controls and Unclassified needing no special protection. Among the options, the set that lists exactly those four levels is the correct one. The other choices introduce nonstandard terms like Classified or Restricted, or repeat Unclassified or omit Top Secret, so they don’t fit the typical four-level scheme.
