Radar is an acronym for which phrase?

• A. Radio Detecting And Ranging
• B. Radio Distinguishing And Responding
• C. Radio Detecting And Ranging
• D. Radio Direction And Ranging

Answer: (C)

Radar is an acronym that describes what the system does: it uses radio waves to locate objects and figure out how far away they are. The word “Radio” shows the medium used, “Detecting” refers to finding targets, and “Ranging” means measuring distance to them. The other options change Detecting to words like Distinguishing or Responding, or swap Detecting for Direction, which would alter the meaning and don’t match how radar is defined. So the phrase that fits is Radio Detecting And Ranging.
