The correct answer is option 2. It states that 0° longitude corresponds to the Equator, which is incorrect. The Equator is actually the line of 0° latitude. Longitude lines run vertically and measure distances east or west of the Prime Meridian, which is the line of 0° longitude. The Prime Meridian is located in Greenwich, England, and is used as the starting point for measuring longitude. On the other hand, the Equator is a line of 0° latitude that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Latitude lines run horizontally and measure distances north or south of the Equator. Therefore, option 2 is incorrect as it incorrectly pairs the Equator with 0° longitude.
