When using a GPS for tracking to the next waypoint, a deviation indication is shown by a vertical bar and dots to the left and to the right of the bar. What statement describes the correct interpretation of the display?

The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection depends on the operating mode of the GPS.

The deviation of the bar from the center indicates the track error as absolute distance in NM; the scale for full deflection is +-10 NM.

The deviation of the bar from the center indicates the track error as angular distance in degrees; the scale for full deflection is +-10°.
