Solution
The correct option is B 180° The International Date Line is roughly based on the 180° Meridian of Longitude and runs down the middle of the Pacific Ocean. It is located exactly half the way around the world from the Prime Meridian in Greenwich. It demarcates the change of one calendar day to the next. It is interesting to note that the International Date Line is not a straight line but deviates East or West at multiple points between the North Pole and South Pole.
