Correct answer: A
Longitude measures the angular distance of a point on Earth's surface relative to the Prime Meridian, which is defined as 0° longitude.
This distance is measured in degrees, ranging from 0° at the Prime Meridian to 180° east or west. The 180° line is known as the International Date Line.
These lines of longitude, also called meridians, are imaginary semicircles that extend from the North Pole to the South Pole, dividing the Earth into the Eastern and Western Hemispheres.
