Correct option is D
The International Date Line refers to 180° Longitude, making the correct answer (D).
- The International Date Line (IDL) is an imaginary line that runs through the Pacific Ocean, roughly following the 180° longitude.
- It serves as the boundary where the date changes—when you cross it from east to west, you move forward by one day, and when you cross it from west to east, you move backward by one day.
- The line is not perfectly straight; it zigzags to accommodate political and territorial boundaries.
