Faraday Cage: A Faraday cage or Faraday shield is an enclosure made of a conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the enclosure is zero. These Faraday cages act as big hollow conductors you can put things into shield them from electrical fields. Any electrical shocks the cage receives, pass harmlessly around the outside of the cage.

Read the above passage carefully and give the answer of the following questions.

Which of the following materials can be used to make a Faraday cage? 

A) Plastic                          

B) Glass  

C) Copper
