The correct answer is C. They run in north and south direction
Step-by-step explanation:
Longitude lines are lines that go from the North Pole to the South and divide the sphere of the Earth into East and West. The main longitude line is known as the prime meridian, which represents 0°, and the maximum longitude lines mark is 180° east or west. Moreover, this concept complements the latitude concept that divides the sphere of Earth into North and South, and includes the equator line. In this context, the true statement about longitude lines is that "they run in a north and south direction" because these are vertical lines that determine how west or east a location is.
