AI Explanation

The correct answer is: Q (Quick Flashing) Under the IALA-A Buoyage System, a port hand mark (a buoy marking the port side of a channel) would not show a Quick Flashing (Q) light characteristic. Port hand marks typically display a Flashing (F) or Occulting (Oc) light characteristic instead. The other answer choices are incorrect because: A) Group Flashing (2+1) is not a standard light characteristic for a port hand mark. B) Continuous Bright (B) is also not a standard light characteristic for a port hand mark. C) Isophase (C) is not a standard light characteristic for a port hand mark. D) Morse Code (D) is not a standard light characteristic for a port hand mark.
