Question 1470Navigation General

The correct answer is C) arc. When determining a line of position using radar range from an identified point on the coast, the resulting line of position will be an arc. This is because the radar range measurement represents the distance from the radar to the identified point, which forms a circle around the radar. When this circle intersects the coastline, the resulting line of position is an arc. The other options are incorrect because a parabola is not the correct geometric shape, a line parallel to the coast would not represent the radar range, and a straight line would not accurately depict the arc formed by the radar range measurement.
