B. Equator

Explanation:

The equator is the plane perpendicular to the axis of rotation of the planet and passing through its center. Divide the surface of the planet into two parts: the northern hemisphere and the southern hemisphere. By definition, the latitude of the equator is 0 °. The plane of the equator "cuts" the surface of the planet in an imaginary line (a maximum circle) that is equidistant - it is exactly at the same distance - from the geographical poles. The equatorial circumference of the Earth measures about 40,075 km. Its radius is 6,378 km. The line of the equator is the point closest to the sky due to the shape of the Earth.
