If the result of loading a vessel is an increase in the height of the center of gravity, there will always be an increase in the __________.

Correct Answer: Option D — vertical moments

Vertical moments are defined as the product of weight and its vertical distance from the reference point (the keel). If the center of gravity rises, it implies that weights have been added or shifted upward, which mathematically necessitates an increase in the sum of the vertical moments of the vessel.
