Signals Intelligence (SIGINT) involves collecting intelligence from where?

• A. It involves collecting intelligence from air quality sensors
• B. It involves open-source news analysis
• C. Signals Intelligence (SIGINT) involves collecting intelligence from communications, information systems, and providing it to customers across the U.S. government
• D. It tracks product sales data

Answer: (C)

Signals Intelligence focuses on intercepting and analyzing signals from communications and information systems to produce intelligence for decision-makers. This means collecting data from voice and text communications, emails, messaging, and other data transmissions, as well as the traffic and metadata from networks, cables, satellites, and similar channels. After collection, analysts process and interpret the signals to provide actionable insights to customers across the U.S. government.

Other options don’t fit because air quality sensors gather environmental data, open-source news analysis is OSINT (open-source intelligence), and tracking product sales data is commercial/business data rather than intelligence derived from intercepted signals.
