You are sailing south on the Intracoastal Waterway (ICW) when you sight a red nun buoy with a yellow triangle painted on it. Which statement is TRUE?

Correct Answer: Option C — The ICW and another waterway coincide in this geographical area.

Yellow symbols on ICW aids indicate that the ICW and another waterway coincide in that area. The yellow triangle signifies the aid is part of the ICW system. Mariners must follow these symbols to ensure they remain on the intended ICW route when multiple channels overlap in a single geographic location.
