Show answer and explanation

Answer: C. Zero

Answer: C. Zero
Explanation: Weight is the gravitational force acting on an object (W = mg). As you go deeper into the Earth, the mass of the sphere of Earth pulling you toward the center decreases. At the very center of the Earth, the gravitational pull from all surrounding directions cancels out perfectly, making the net gravitational force and therefore the weight exactly zero
