The answer is d, coppr rod, which means the copper rod cannot be charged by friction because both it is a highly conducting material.
As only nonconductive materials can be charged by friction highly conductive copper rod cannot be charged by friction.
The frictional charging procedure outcomes in a transference of electrons between the two objects that are scrubbed together for friction.
