This question tests how display orientation follows the ship’s movement over ground. The course-up orientation rotates with the ship’s course, so as the track over ground changes, the top of the display turns to keep the current course direction at the top. This is different from north-up, which stays fixed to true north regardless of how the ship turns, and from heading-up, which rotates with the ship’s heading (where the bow is pointing) not necessarily the actual path. The idea that all orientations rotate with the ship’s course isn’t correct because north-up would remain anchored to geographic north. So, course-up is the orientation that rotates with the ship’s course. For example, if your course changes from 030 to 045 degrees, the course-up display would rotate so 045 degrees appears at the top.
