The righting moment can be determined by multiplying the displacement by the __________.

Correct Answer: Option C — righting arm (GZ)

Righting moment is defined as the product of displacement and the righting arm (GZ). Per naval architecture principles used in 46 CFR stability assessments, GZ represents the horizontal distance between the center of gravity and the center of buoyancy, which generates the torque necessary to return a vessel to upright.
