The correct answer is A) they measure distance north and south of the equator.
The statement that accurately describes lines of latitude, also called parallels, on a map is "they measure distance north and south of the equator."
Latitude lines are the imaginary lines or parallels that run around the globe, horizontally. These lines are equidistant from each other. The degree of latitude is 69 miles apart. The Equator is located at zero degrees latitude, the imaginary line that divides the Earth in the northern hemisphere and southern hemisphere.
