Any regular set of parallels and meridians upon which a map can be drawn is called

• A. Graticule
• B. Datum
• C. Map Projection
• D. Grid

Answer: (C)

The main idea here is recognizing the named reference system formed by lines of latitude and longitude on a map. This network of regular lines is called the graticule. It provides the coordinate framework—parallels (latitudes) and meridians (longitudes)—that lets you locate any point on the Earth. The graticule is about the reference grid itself, not about how the globe is projected onto a flat map.

A map projection, by contrast, is the method used to represent the curved surface on a plane, which changes shapes and distances. A datum is the reference surface (the model of Earth) used to position coordinates. A grid is a general term that can refer to any grid-like layout, but the precise term for the latitude–longitude network is graticule.
