In which frequency band does a search and rescue transponder operate?

Explanation:
Search and rescue transponders are radar beacons that respond to interrogation from a ship’s radar. They operate in the 9 GHz range, the X-band, which is the frequency band used by most maritime radar. When a rescue radar scans over the transponder, the SART replies with a distinctive radar signal that appears on the interrogating radar screen as a pattern of dots or blips, helping the operator determine the survivor’s bearing and range. The other frequency options aren’t used for this purpose, as they don’t match the standard maritime radar band for SARTs.
