Answer & Explanation
The correct answer is Option C: C) free the life raft from a sinking vessel.
The hydrostatic release unit (HRU) is designed to release the painter line of a liferaft when submerged to a specific depth (usually 1.5–4 meters). If inoperative, it will not free the liferaft from the sinking vessel.
