Answer & Explanation
The correct answer is Option B: It prevents release of the hooks until the keel of the boat is fully under water.
The hydrostatic interlock is a critical safety mechanism designed to prevent the accidental release of lifeboat hooks while the craft is still suspended in the davits; it only allows release once the buoyancy of the water triggers the mechanism.
