Official USCG Answer & Rule Citation
Correct Answer: Option B — very quick flashing
Lighted cardinal marks utilize either very quick flashing (VQ) or quick flashing (Q) white lights to distinguish their purpose and quadrant. Group flashes determine the specific quadrant (3, 6, or 9 flashes), preventing confusion with lateral or danger markers.
