Which of the following propulsor types represents the proper terminology for electric propulsion where the drive motors are outside the ship's hull?

Correct Answer: Option B — Azipod propulsor

Azipod propulsors are electric drive units mounted in a steerable pod outside the ship's hull. This configuration eliminates the need for long shafting and rudders, providing 360-degree thrust vectoring. These systems are highly efficient for modern cruise ships and icebreakers requiring superior maneuverability and space-saving machinery arrangements.
