Consider the following statements about Equator and choose the correct option :
(A) The equator is a real line running on the globe, which divides it into two equal parts.
(B) The equator is the longest latitude.
(C) The equator represents the 180° latitude.

Correct option is B

The correct answer is (b).
The equator is the longest latitude, measuring 40,075 kilometers. It is also the only latitude that is a great circle, meaning that it is the shortest distance between any two points on the equator.
The equator is not 180 degrees latitude. The equator is 0 degrees latitude, and the other latitudes range from 0 degrees to 90 degrees north and south.
