Correct Answer is A - As a vessel sinks to a depth of 15 feet, the hydrostatic trip releases the life raft container from its cradle by Breaking the weak line. The hydrostatic device is activated by water pressure at that depth, which snaps the weak link that secures the raft. Here's a breakdown of why the other options are incorrect: B. Releasing the tie-down stop: The tie-down strap or stop holds the raft in place until the hydrostatic release triggers it. C. Pulling the operating cord: The operating cord is a manual release mechanism, used if you don't want to wait for the hydrostatic release or if it fails. D. Releasing the CO2 Canister: The CO2 canister is part of the inflation system, not the initial release mechanism from the cradle.
