Vertical coordinate systems always use linear units to measure elevation or depth (e.g., meters, feet). This differs from horizontal coordinate systems, which may use angular units (degrees) for geographic coordinates.
Angular units (Option B) apply to latitude and longitude in horizontal systems.
Direction units (Option C) apply to bearings or azimuths, not elevation.
Therefore, the correct answer is A.
