How does an icebreaker normally free a ship which has become beset while navigating independently?

Correct Answer: Option C — By approaching from the stern and crossing ahead at an angle of 20° to 30° to the beset ship's course

Icebreakers free a beset ship by moving astern and crossing ahead at a 20 to 30-degree angle. This maneuver generates pressure waves and breaking action in the ice track directly ahead of the trapped vessel without risking a collision.
