-
A.
WGS84
chosen
WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
-
B.
GRS80
GRS80 is a geodetic reference ellipsoid defined in 1980 that serves as a standard mathematical model of the Earth's shape for modern mapping and surveying systems.
-
C.
Bessel ellipsoid
The Bessel ellipsoid is a historical reference ellipsoid of the Earth defined in the 19th century for geodetic and cartographic purposes, particularly in Europe.
-
D.
Clarke 1866 ellipsoid
The Clarke 1866 ellipsoid is a historically important reference ellipsoid used as the geodetic basis for many 19th- and 20th-century national mapping systems, particularly in North America.
-
E.
Airy Modified ellipsoid
The Airy Modified ellipsoid is a slightly adjusted version of the Airy ellipsoid used as the reference surface for mapping and geodetic calculations in systems such as the Irish grid reference system.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
