What statement concerning the orientation and welds of adjoining shell plates is true?

Correct Answer: Option A — The shell plates (or strakes) run horizontally in a fore and aft direction and any horizontal welds are called "seams" and any vertical welds are called "butts".

Shell plating strakes are arranged longitudinally along the hull. In accordance with standard shipbuilding terminology, the horizontal joints between these strakes are defined as seams, while the vertical joints connecting the ends of the plates are defined as butts, ensuring proper structural continuity.
