Dear student,

Asumming earth to be perfectly spherical, all point masses uniformly spread across the whole Earth will pull the body put at its center symmetrically in all directions. All these forces will cancel each other resulting in net force to be zero. Hence the acceleration due to gravity at center of the earth is zero.
