Under electrostatic conditions, the electric field just outside the surface of any charged conductor
 
  A) is always parallel to the surface.
  B) is always zero because the electric field is zero inside conductors.
  C) is always perpendicular to the surface of the conductor.
  D) is perpendicular to the surface of the conductor only if it is a sphere, a cylinder, or a flat sheet.
  E) can have nonzero components perpendicular to and parallel to the surface of the conductor.
