• A. A device that measures distance to satellites
• B. A map projection technique
• C. System for capturing, storing, checking, and displaying data related to positions on Earth's surface
• D. A set of geographic symbols

Answer: (C)

Geographic Information System is a system for capturing, storing, checking, and displaying data related to positions on Earth's surface. It combines spatial information (where things are) with attribute data (what they are) and lets you manage that data in a database, verify its accuracy, and visualize it through layered maps and queries. This integration enables capturing new spatial data, performing analyses (like finding nearby features or overlapping areas), and presenting results in meaningful map formats. The description captures the full idea of GIS as a comprehensive system, not just a single device, a map projection method, or a set of map symbols. A GPS device measures distances to satellites, a map projection technique handles how to flatten the globe onto a map, and a set of symbols represents features on a map; none of these alone describe the complete GIS.
