When a negatively charged plastic rod touches a metal sphere, the negative charges (electrons) from the rod are repelled by the excess negative charge on the rod and will induce a movement of charges within the metal sphere. Since the sphere is conductive, electrons will redistribute themselves.
Ultimately, the negative charges will spread out evenly across the surface of the metal sphere. This is because charges in conductors move until they reach an equilibrium where the electric potential is uniform throughout the conductor.
So, the correct response is: **They spread out evenly.**
