Correct option is C
The
azimuth is the angle measured clockwise from the true north (true meridian) to the survey line. It is used to describe the direction of the survey line relative to the true north.
True bearing: Refers to the angle measured from the true north to the survey line, but not necessarily the smaller angle.
Arbitrary meridian: A reference direction chosen for convenience, not the angle itself.
Azimuth: Correct, as it specifically denotes the angle between the true meridian and the survey line.
Magnetic bearing: Measures the angle relative to the magnetic north, not the true north.
Therefore, the correct answer is (c) Azimuth.
