Question 685Navigation General

The correct answer is C) 360 degrees. A magnetic compass card is marked in 360 degrees because this corresponds to the full circle of a compass. The compass rose, which is the markings on the compass card, is divided into 360 equal segments, each representing one degree. This allows for precise navigation and measurement of headings and bearings. The other options are incorrect because: A) 90 degrees would only represent a quarter of the compass circle, B) 180 degrees would only represent half the compass circle, and D) 400 degrees is not a standard compass marking.
