Of the four light characteristics shown in illustration D019NG below which one does NOT represent a safe water mark of the IALA Buoyage System?
AI Explanation
The correct answer is A.
The IALA Buoyage System defines four primary light characteristics: fixed, flashing, occulting, and isophase. Option A, which depicts a fixed light, does not represent a safe water mark in the IALA Buoyage System. Safe water marks are typically indicated by a white light with a red sector or a white light with a green and red sector. The other options, B (flashing), C (occulting), and D (isophase), can represent safe water marks in the IALA Buoyage System.
