AI Explanation

The correct answer is D) All of the above. Lines of position can be hyperbolas, arcs, or straight lines, depending on the navigation method used. Hyperbolas are obtained from celestial observations, arcs are obtained from radar ranges, and straight lines are obtained from bearings or cross-bearings. All three types of lines of position are commonly used in marine navigation and are accepted as valid on the US Coast Guard Captain's License Examinations.
