B
C
C
D
D
AI Explanation
The correct answer is B. The illustration D017NG shows a buoy fitted with a racon (radar beacon). When a racon is detected by the radar, it will produce a distinct "dash" or "bloom" on the radar display, as shown in option B. This is the expected presentation on the PPI (Plan Position Indicator) when radar scanning for a buoy with a racon. The other options do not accurately represent the radar presentation of a racon-equipped buoy. Option A shows a simple target echo, option C depicts a more complex radar image, and option D does not appear to show a racon indication at all.
