The answer is: [C]: the Prime Meridian. ___________________________________ The Prime Meridian; which is an imaginary line and arbitrarily chosen, runs through 0<span>° longitude and runs through Greenwich, English. __________________________________________________ The Equator runs through 0</span><span>° latitude. _____________________________ The North Pole is located at 90</span><span>° north latitude and is not an imaginary line. Technically, any longitude value from 0</span>° to 180°—East or West—would be the correct longitude for the North Pole; however, by convention, the coordinates are 90°N, 0<span>°W. </span><span>____________________________ The South Pole is located at 90</span>° south latitude and is not an imaginary line. Technically, like the North Pole, any longitude value from 0° to 180°—East or West—would be the correct longitude for the South Pole; however, by convention, the coordinates of 90°S, 0°E; or even: - 90° S, 0° E. ________________________________________
