An inflatable liferaft should be manually released from its cradle by __________.

Correct Answer: Option B — pushing the button on the hydrostatic release

Hydrostatic release units feature a manual release capability via a manual push-button or lever that bypasses the pressure-activated knife mechanism. Under 46 CFR and SOLAS standards, this enables rapid manual deployment of the liferaft cradle securing strap without relying on water submergence during an abandon-ship emergency.
