C Correct answer
Explanation

The International Date Line roughly follows the 180° meridian. When you cross it, the calendar changes by one day. Two points on opposite sides are 24 hours apart in time, with one being a day ahead of the other. This is why crossing east to west makes you 'gain' a day and west to east makes you 'lose' a day.
