Copper is a very conductive nonprecious metal. The single electron in its outer shell is mobile and can equalize any local electrostatic charge. The correct option is therefore;
- Equalize any local electrostatic charge
Reason:
Due to its structure, copper is the second to only silver as the most conductive metal, such that electricity can easily flow through it as the electron in its outer shell can be easily removed so as to become net positively charged and attract another electron from a source, creating current flow
In the manner by which electricity is efficiently conducted, the mobile electron in its outer shell enables copper to neutralize any net local electropositive charge thereby becoming positively charged to more efficiently equalize any net local negative charge
- Copper is a good conductor of charge and, it can therefore neutralize any local electrostatic charge
