    The correct answer is A. Faraday cage.

    Explanation:

    A Faraday cage is a metal box that protects against static electric fields. It owes its name to the physicist Michael Faraday, who built one in 1836. They are used to protect against electric shock, since inside the electric field is null.

    The operation of the Farday cage is based on the properties of a conductor in electrostatic equilibrium. When the metal box is placed in the presence of an external electric field, the positive charges remain in the network positions; electrons, however, which in a metal are free, begin to move.
