An orange and white buoy indicating a vessel-exclusion area will be marked with what symbol?

Correct Answer: Option B — Diamond with a cross

The U.S. Aids to Navigation System, per 33 CFR 62.33, mandates that a diamond with a cross inside indicates a vessel-exclusion area. This symbol is displayed on white buoys with orange bands to clearly warn mariners that entry into the marked area is prohibited for safety or regulatory reasons.
