Answer:
C-Electricity will flow if the electrons are bound tightly to their atoms in the material.
Step-by-step explanation:
The flow of electricity through a material is determined by the condition of the electron which make of the atoms of the material. For example, in iron metal, the electron of the material is bounds tightly to their atoms. Do to this reason, the electricity can flow freely inside them unlike the plastic material which has no tightly bound electrons.
