Answer: Option D

Solution(By Examveda Team)

All meridians are of equal length; each is one-half the length of the equator. All meridians converge at the poles and are true north-south lines. The equator is located at 0° latitude, which means it is located at the circunference of Earth. Earth is shaped like a sphere, and the circumference of a sphere is the longest distance around any part of the sphere. Therefore, this makes the equator the longest line of latitude.
