    The answer is actually A: celestial

    Explanation:

    The answer is not azimuth-altitude because using that system means that the coordinates change with your geographic location. With celestial, you can coordinate the object's location using right ascension and declination no matter what latitude you are standing at.

    Answer : Celestial or azimuth - altitude

    Explanation:

    Celestial : The celestial coordinates that are analogous to longitude and latitude are called RA and Dec.

    RA = Right Ascension

    Dec = Declination

    RA is the measured in unit of time and Dec is measured in degree.

    The equatorial coordinate system is the projection of the latitude and longitude coordinate system on the celestial sphere.

    Azimuth - altitude : Azimuth - altitude define the location of an object in the sky.

    The altitude is the distance of an object appears to be above the horizon.

    The Azimuth of the object is the angular distance along the horizon to the location of the object.
