Question 1850 Deck Safety

The correct answer is B) inner bottom. The inner bottom is the plating indicated by the letter N in the illustration D033DG. The inner bottom is the structural plating that forms the bottom of a ship's double bottom, providing additional strength and buoyancy. This is a key structural component that is regulated and defined in maritime engineering standards for vessel construction. The other answer choices are incorrect because they do not accurately describe the plating indicated by N in the given illustration. Floor riders, tank-top rider plating, and ceiling are different structural elements of a ship's construction, but they do not match the specific component shown in this diagram.
