Solution

The correct option is C A copper rod
Copper is a good conductor. So, charges flow very easily through the surface of copper. If a copper is rubbed with some material, the charge generated, instead of staying on the copper rod surface, flows throw it and reaches the Earth by conducting through our body. So, a copper rod can not be charged by rubbing or friction.
