Each OSV must carry __________.

Correct Answer: Option D — All of the above

46 CFR 133.130 and 133.150 mandate that OSVs carry specific life-saving equipment, including rocket parachute flares for distress signaling, life buoys with buoyant lines for man-overboard recovery, and a Category I 406 MHz EPIRB for satellite-based emergency position reporting. All these items are essential for regulatory compliance and safety.
