D
L
AI Explanation
The correct answer is D. The letter 'L' in illustration D033DG indicates a longitudinal, which is a structural member that runs lengthwise along the vessel. Longitudinals provide longitudinal strength and rigidity to the hull of the vessel. This is a standard concept in naval architecture and shipbuilding that is tested on US Coast Guard Captain's License Examinations. The other answer choices are incorrect because 'M' indicates a margin, 'E' indicates an edge, and 'C' indicates a cross-section, none of which are longitudinals.
