Which set correctly lists three intelligence disciplines and a brief example of each?

• A. HUMINT (human intelligence), SIGINT (signals intelligence), IMINT (imagery intelligence)
• B. HUMINT (human intelligence), GEOINT (geospatial intelligence), MASINT (measurement and signatures intelligence)
• C. OPORD (Operations Order), WARNORD (warning order), FRAGORD (fragmentary order)
• D. CMO (Civil-Military Operations), ISR (Intelligence, Surveillance, and Reconnaissance), UAS (Unmanned Aerial System)

Answer: (A)

Different intelligence disciplines are defined by how information is gathered: from people, from electronic signals, or from imagery. HUMINT refers to information obtained directly from human sources—agents, informants, interviews. SIGINT covers signals like communications or radar emissions intercepted with specialized equipment. IMINT uses imagery captured by cameras, satellites, or aerial platforms to analyze scenes, facilities, or activities. This trio demonstrates distinct collection methods that together provide a broad view: human-sourced insights, technical signal data, and visual imagery for terrain and activity assessment. The other options mix in terms that aren’t three clear, separate intelligence disciplines with concise examples in the same format, so they don’t fit as neatly. Therefore, this set best matches the prompt.
