A A
B B
C C
D D
AI Explanation

The correct answer is A. The light characteristic "Fl(2+1)" refers to a light that displays a group of 2 flashes followed by 1 single flash, repeating continuously. This pattern is classified as a "Composite Group Flashing" light characteristic, which is designated by the letter "A" according to the International Association of Lighthouse Authorities (IALA) standards for maritime navigational aids. The other options are incorrect because they do not match the specific "Fl(2+1)" light pattern described in the question.
