Which term refers to secretive surveillance that is not openly visible?

• A. Coded Radio Communications
• B. Cover
• C. Covert
• D. Overt

Answer: (C)

Covert refers to actions that are deliberately hidden from view. In surveillance, covert means the operation proceeds without drawing attention or anyone being aware that surveillance is taking place. That hidden, not openly visible nature is exactly what the question is asking about. By contrast, overt surveillance is obvious and visible, like cameras or officers clearly watching a scene. Coded radio communications deal with securing messages rather than the visibility of the surveillance itself, and cover relates to the disguise or false identity an undercover investigator might use. So the term that best fits “secretive surveillance that is not openly visible” is covert.
