The correct answer is C) shows a longitudinal side elevation. The sheer plan is a view that shows the longitudinal side elevation of a ship, depicting the curved or "sheer" shape of the deck from bow to stern. This plan is an important component of ship design and construction, as it provides a detailed profile view of the vessel's overall shape and dimensions. The other answer choices are incorrect because: A) the sheer plan is typically drawn for both the port and starboard sides, not just the port side; B) the sheer plan does not depict the forebody and afterbody offset from the centerline; and D) the sheer plan is not an endwise view of the ship's molded form, but rather a longitudinal side elevation.
