Question 2019 Deck Safety

The correct answer is A) G, which represents the center of gravity in illustration D001SA. The center of gravity (G) is the point at which the weight of the vessel is considered to be concentrated. This is a critical factor in determining the stability of a vessel, as the position of the center of gravity relative to the center of buoyancy (B) affects the vessel's righting moment and overall stability. The other options are incorrect because M represents the metacenter, which is the point where the line of action of the buoyant force intersects the vessel's centerline, and GZ represents the righting arm, which is the distance between the center of gravity and the center of buoyancy.
