SSI stands for which phrase?

• A. Security Sensitive Information
• B. Sensitive Security Information
• C. Security and Sensitive Information
• D. Secure Security Information

Answer: (B)

In this area, SSI refers to information related to transportation security that, if disclosed, could compromise safety. The official phrase is "Sensitive Security Information," so the term in question matches that wording exactly. This designation tells you that the information is restricted and should only be shared with authorized personnel, marked appropriately, and handled through secure channels. It may be exempt from public disclosure in many cases.

The other phrasings don’t align with how this term is defined in regulations, which is why they aren’t correct. They either flip the order of the words, add an extra conjunction, or use a word (like "Secure") that isn’t the established terminology.
