What is another name for the Prime Meridian?

Explanation:
The Zero longitude line used to measure how far east or west a location is runs from pole to pole and was fixed at Greenwich, outside London. Because it passes through Greenwich at the Royal Observatory, this line is commonly called the Greenwich Meridian. It serves as the reference point for longitude, with lines to the east and west measured from it. The other options aren’t correct because the International Date Line marks a roughly opposite longitude that determines calendar date, the Equator is the 0-degree line for latitude (not longitude), and the Tropic of Cancer is a latitude line at about 23.5 degrees north.
