- B. Two all-round red lights in a vertical line only
- C. Three all-round lights (red-white-red) in a vertical line, plus sidelights and a sternlight
- D. Two all-round red lights in a vertical line, plus a masthead light, sidelights, and a sternlight
Why A is correct
Under 33 CFR §83.27(a), a NUC vessel exhibits two all-round red lights in a vertical line at all times, and when making way adds sidelights and a sternlight. No masthead light is prescribed for NUC vessels, and the red-white-red combination belongs to RAM vessels.
