70% to pass

The description "Racon" beside an illustration on a chart would mean a _______________.

A radar conspicuous beacon
B circular radio beacon
C radar calibration beacon
D radar transponder beacon
AI Explanation

The correct answer is D) radar transponder beacon. A "racon" (short for radar beacon) is a radar transponder that responds to radar signals, transmitting a coded signal that indicates its location on the chart. This helps vessels with radar locate the racon's position, which is marked on nautical charts. The other options, while related to beacons, do not accurately describe the function of a racon as a radar transponder.
