- A. A smoke signal giving off white-colored smoke
- ✓ A smoke signal giving off orange-colored smokeCorrect
- C. A continuous flashing white light at 30 flashes per minute
- D. A square flag displayed alone without any other shape
Why B is correct
33 CFR §87.01(j) specifically lists a smoke signal giving off orange-colored smoke as a recognized distress signal. White smoke is not listed, and a square flag must have a ball or ball-like shape above or below it per §87.01(g). A high-intensity white light must flash at 50–70 times per minute, not 30.
