Two Spheres Are Placed near (But Not Touching) Each Other

Two spheres are placed near (but not touching) each other on an insulated table. Sphere A is made of a nonconducting material and carries a net charge, while sphere B is made of a conducting material and is neutral. The statement that best describes the electrostatic force between the spheres is

A) the force is attractive if A is positively charged, and repulsive if A is negatively charged.
B) the force is repulsive irrespective of the charge on A.
C) the force is attractive irrespective of the charge on A.
D) there is no electrostatic force since B is neutral.
