A Correct answer
Explanation

A great circle is the largest possible circle that can be drawn on a sphere, dividing it into two equal halves. The Equator is the only latitude that forms a great circle because it passes through Earth's center and lies in a plane perpendicular to Earth's axis. All other latitudes are small circles.
