Where does the Prime Meridian pass through?

Explanation:
The starting point for measuring longitude is the Prime Meridian, defined as 0 degrees. This line runs from the North Pole to the South Pole and passes through the Royal Observatory in Greenwich, England. That specific location in Greenwich was chosen as the global reference in the 1884 International Meridian Conference, making Greenwich the standard for longitude and for timekeeping (GMT/UTC). So maps and navigation reference longitude measurements from this line. The other cities listed are not on the 0 degree line, which is why Greenwich, England is the correct choice.
