• A. 1 short every sec
• B. 2 short, 1 long every 6-10 sec
• C. 3 short every 10 sec
• D. 9 short every 15 sec

Answer: (C)

The east cardinal buoy indicates its position and navigational significance through a specific flashing light sequence that is unique to it. The correct answer is that it signals its flashing sequence with three short flashes every 10 seconds. This distinctive pattern allows mariners to identify the buoy's location and direction.

East cardinal buoys are essential for maritime navigation as they denote safe passages to the east of the buoy. The three short flashes serve as a clear and recognizable signal for vessels, helping them to navigate safely in relation to the cardinal directions indicated by the buoy.

Understanding the specific sequences associated with cardinal buoys is vital for safe navigation, as it aids in situational awareness and can prevent mishaps at sea.
