  A) Yes, because electric fields have energy and all forms of energy are associated with material particles.
  B) No, because electromagnetic waves are able to cross regions of empty space containing no material particles.
  C) Yes, because the forces exerted by electric fields are always exerted on material particles such as atoms.
