🔍 Key Concepts

• Review the standard shapes of can, nun, spar, and pillar buoys in the U.S. Aids to Navigation System (IALA B). • Notice the difference in height and profile between low, squat buoys and taller, more tower‑like buoys. • Focus on which buoy type has a broad base with a narrower, tower‑like structure rising from it.

💭 Think About

• Which option shows a buoy that looks more like a short tower on a base rather than just a simple can, cone, or thin pole? • Look at the overall silhouette: which letter’s buoy could support a light or structure above the water because of its stronger, broader base? • Ask yourself: which shapes are clearly a basic cylinder, a thin pole, or a cone, and which remaining one best fits the idea of a pillar?

✅ Before You Answer

• Eliminate the buoy that is simply a low cylinder (classic can shape). • Eliminate the buoy that is just a thin vertical pole (spar buoy). • Eliminate the buoy that is a simple cone/nun shape without a distinct base and tower. The remaining one should match the pillar buoy.
