Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

At Earth's center, a body is equidistant from all surrounding mass. Gravitational forces from all directions cancel out completely, resulting in zero net gravitational force and thus g = 0. Option A is incorrect because g is maximum at the surface, not the center. Option B is wrong since g varies with depth. Option D is misleading - g is zero, not just minimum.
