AI Explanation
The correct answer is A) surge. Surge refers to the horizontal fore and aft movement of a vessel, which is the longitudinal motion along the vessel's length. This is one of the six degrees of freedom of a vessel's motion, the others being sway (lateral motion), heave (vertical motion), roll, pitch, and yaw. The other options are incorrect because sway refers to lateral or sideways motion, heave refers to vertical up-and-down motion, and yaw refers to the rotational motion around the vertical axis.
