B Correct answer
Explanation

An electroscope is a device that can be used to test for the presence of charge, or that can be charged. An electroscope is made from conducting material (generally metal). Charge is free to flow on a conductor, and if you put charge at a particular point it will distribute itself over the surface of the conductor.
