D Correct answer
Explanation

Lines of longitude, also known as meridians, run from the North Pole to the South Pole but are used to measure distances east or west of the Prime Meridian. Therefore, they measure distance in an east-to-west direction. Lines of latitude, on the other hand, measure distance in a north-to-south direction.
