Stability is determined principally by the relationship of the center of gravity and the __________.

Correct Answer: Option B — center of buoyancy

Stability is governed by the interaction between the center of gravity and the center of buoyancy. When a vessel heels, the center of buoyancy shifts, creating a righting arm (GZ) if the center of buoyancy moves outboard of the center of gravity, which acts to return the vessel to upright.
