Which option lists a valid combination of platforms used for remote sensing data collection?

• A. Ground vehicles, Submarines, Balloons
• B. Drones, Boats, Cars
• C. Satellites, Aircraft, Unmanned aircraft
• D. Mobile phones, Laptops, Tablets

Answer: (C)

Platforms for remote sensing are the carriers that host sensors and collect data from above or beyond the surface. The best combination is satellites, aircraft, and unmanned aircraft because it covers the main ways we observe the Earth: satellites provide broad, repeat coverage from space; piloted aircraft offer higher-resolution imagery and access to different angles and regions; and unmanned aircraft (drones) bring flexible, cost-effective data collection at various altitudes to target specific areas or rapid-response needs. Other options mix in submarines or ground-level devices, which aren’t standard platforms for routine remote sensing data collection, or rely on personal devices like mobile phones or tablets that aren’t primary sensing platforms for wide-area observation.
