A the equator
B a great circle
C a meridian
D a small circle
AI Explanation

The correct answer is B) a great circle. A plane that cuts the Earth's surface at any angle and passes through the center of the Earth will always form a great circle. A great circle is the largest possible circle that can be drawn on the surface of a sphere, and it divides the sphere into two equal halves. The other options are incorrect because: A) The equator is a specific great circle that lies in a plane perpendicular to the Earth's axis. C) A meridian is a great circle that passes through the North and South poles. D) A small circle is a circle on the surface of a sphere that does not pass through the center of the sphere.
