The correct answer identifies that Distance Measuring Equipment (DME) operates in the Ultra High Frequency (UHF) range, specifically between 960 to 1215 MHz. This frequency range is significant because DME is used as a navigational aid that provides distance information to pilots by measuring the time it takes for a radio signal to travel to the DME ground station and back. The UHF band is suitable for this purpose as it allows for precise distance measurements and is less susceptible to interference than frequencies in lower ranges.

DME provides critical data for navigation, especially during approaches and in areas with complex air traffic. Its operation within UHF offers the clarity and reliability needed for safe and efficient navigation, which is crucial for maintaining accurate distance readings in aviation.
