    Read the following text and answer the following questions on the basis of the same:
    Faraday Cage: A Faraday cage or Faraday shield is an enclosure made of conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the encloser is zero. These Faraday cages act as big hollow conductors you can put things in to shield them from electrical fields. Any electrical shocks the cage receives, pass harmlessly around the outside of the cage.
    Which of the following material can be used to make a Faraday cage?

    A) Plastic

    B) Glass

    C) Copper

    D) Wood
