Which set lists the three aerial platforms best suited for remote sensing?

• A. Satellites, aircraft, and unmanned aircraft
• B. Balloons, aircraft, and ships
• C. Satellites, balloons, and ships
• D. Satellites, submarines, and unmanned aircraft

Answer: (A)

Remote sensing relies on platforms that carry sensors through the air or space, so the best three aerial options are satellites, aircraft, and unmanned aircraft. Satellites provide wide, repetitive coverage and can carry a range of sensors for global monitoring. Aircraft offer higher spatial resolution and flexibility, allowing missions to be planned at specific altitudes and routes. Unmanned aircraft deliver cost-effective, high-resolution data for targeted areas and can operate in situations where manned flights are impractical. The other sets mix non-aerial platforms (like ships or submarines), or combine aerial with non-aerial elements, which isn’t consistent with using three aerial platforms for remote sensing. Balloons are airborne, but the inclusion of ships makes that set not three aerial platforms, so that option isn’t the best fit.
