The arc of the compass card is divided into how many degrees?

The compass card is divided into 360 degrees, representing the full circle around the navigator's point of view. This division allows navigators to precisely indicate direction and headings. Each degree corresponds to a specific direction, making it easy to use for navigation and piloting.

Having the compass card set at 360 degrees facilitates precise navigation that is necessary for safely steering vessels. This system is universally recognized and is critical in maritime operations, where accurate directional guidance is vital for safe travel and positioning at sea. The other options do not encompass the complete range of direction that is essential in navigation, which is why they are not correct.
