Explanation:

Gravitational fields cannot be shielded. The mass of the building does attract us slightly upward, but this effect is extremely small and not the reason for the weight - change perception. In reality, the main factor affecting weight is the distance from the Earth's center of mass, and the building's mass attraction is negligible in comparison. So the answer is none of these.

Answer:

none of these
