To represent the ellipsoid in two dimensions, we use a projection called

Representing the Earth’s curved surface on a flat map requires a projection that converts latitude and longitude on the ellipsoid into planar x and y coordinates. The Universal Transverse Mercator projection does this by dividing the globe into a series of zones and applying the transverse Mercator transformation within each zone, which keeps distortion low in a localized 2D area and yields practical coordinates for mapping and engineering tasks. The other options aren’t projections. A Geographic Coordinate System expresses positions with latitude and longitude on the ellipsoid, not a flat plane. The NAD83 and WGS84 are datums that define the reference ellipsoid and how the model aligns to the Earth; they influence measurements but don’t themselves flatten the surface into two dimensions.
