Which of the following best describes what is considered SCI?

• A. Intelligence activities including covert action, intelligence sources or methods, or cryptology
• B. Weather data and climate records
• C. Public press releases
• D. Personal contact information

Answer: (A)

SCI is highly sensitive information about intelligence activities, sources, or methods that requires special handling and access controls. The description that mentions intelligence activities including covert action, intelligence sources or methods, or cryptology matches this idea exactly, since it covers covert operations and the secrecy around sources and cryptographic techniques. Weather data and climate records are typically unclassified, public press releases are openly available, and personal contact information, while sensitive, is not SCI unless it is specifically classified and designated for such handling.
