Solution

The correct option is B
zero

The weight of a body at the centre of earth is zero because value of g is zero. As we move a body closer to the centre of the earth, the mass of the earth between the centre of the earth and the body keeps decreasing. This causes the force acting from the centre of the earth on the body to decrease.
