  A)
 a force of repulsion, because they are like-charged.  Eliminate Reactivate   
  B)
 a force of attraction, because they are oppositely charged.  Eliminate Reactivate   
  C)
 no force, because charges are not transferred by mere contact.  Eliminate Reactivate   
  D)
 no force, because the distance separating the spheres needs to be large.  Eliminate
