The correct answer is C. 180°W or 180°E
Explanation
Planet Earth with its spherical shape has been divided by imaginary lines to establish geographical locations, climatic zones and time zones. These imaginary lines are the Meridians and Parallels. The meridians are imaginary lines that go from the north pole to the south pole and divide the earth by 360 ° in length; of which 180 ° in length are towards the west and 180 ° in length are towards the east taking as reference point 0 ° the Greenwich Meridian, dividing the earth in eastern and western hemisphere.
On the other hand, the parallels are imaginary lines that divide the earth horizontally taking as reference the line of the equator or 0 °, this pattern divides the earth in the northern hemisphere and the southern hemisphere each with 90 ° latitude. So, the correct answer is C. 180°W or 180°E.
