Which of the following is an accurate definition of an azimuth?

An azimuth is defined as the angle between a reference direction and a point of interest, measured in a clockwise direction from the reference direction. The most common reference direction used in geodesy and navigation is true north. Thus, an azimuth is measured in degrees starting from the north and moving clockwise. This means that an azimuth of 0 degrees indicates a direction directly north, whereas 90 degrees would indicate an eastward direction, 180 degrees south, and 270 degrees west.

The emphasis on measuring from north distinguishes azimuth from other directional measurements. For example, if measurements were to start from the south, the convention would differ significantly, which is why option A does not accurately define azimuth. The other options concerning angle measurements of curves and coordinate measurements of points do not relate to the concept of azimuth at all, as they pertain to different aspects of geometry and geographic positioning.
