Final answer:
The correct convention for representing geographic coordinates is that b. latitude is written first, then longitude, such as in the coordinates for Washington, DC: 38° N, 77° W.
Step-by-step explanation:
The correct statement that accurately describes the convention for representing geographic coordinates of latitude and longitude is: b. Latitude is written first, followed by longitude.
When noting geographic coordinates, latitude, which is the position north or south of the equator, is given first and ranges from 0° to 90° North or South. Longitude, indicating the position east or west of the Prime Meridian, is provided second and extends from 0° to 180° East or West. For example, the geographic coordinates for Washington, DC, are expressed as 38° N latitude and 77° W longitude.
