Subtracting the height of the center of gravity corrected for longitudinal free surface effects from the height of the longitudinal metacenter of a MODU yields _______________.

AI Explanation
The correct answer is A) GML. Subtracting the height of the center of gravity corrected for longitudinal free surface effects from the height of the longitudinal metacenter of a MODU (Mobile Offshore Drilling Unit) yields the transverse metacentric height (GML), which is a key stability parameter for MODUs. The other options are incorrect because: B) GM is the transverse metacentric height, which is not the result of the subtraction described in the question. C) KML is the longitudinal metacentric height, which is different from the transverse metacentric height. D) KGL is the vertical distance between the keel and the center of gravity, which is not the result of the subtraction.
