- A. At regular intervals from 30 to 50 times per minute
- ✓ At regular intervals from 50 to 70 times per minuteCorrect
- C. At regular intervals from 60 to 90 times per minute
- D. At regular intervals from 40 to 60 times per minute
Why B is correct
33 CFR §87.01(p) specifies a high-intensity white light flashing at regular intervals from 50 to 70 times per minute as an authorized distress signal. Any other flash rate would not meet the regulatory definition and could be confused with other light signals.
