A magnetic compass card is marked in how many degrees?

A 90
B 180
C 360
D 400
AI Explanation

The correct answer is C) 360 degrees. A magnetic compass card is marked in 360 degrees, which corresponds to the full 360-degree circle. This is the standard for compass cards, as it allows for precise navigation and heading measurements. The other options are incorrect because 90 degrees represents a quarter-circle, 180 degrees represents a half-circle, and 400 degrees is not a standard compass marking.
