Answer 1

The electrons in copper (Cu) are loosely bound to the nucleus.

Explanation: Copper is a metal with delocalized (loosely bound) conduction electrons that move easily under an electric field, giving low resistivity. Carbon fibers have electrons tied up in covalent bonds (so much less free charge), so they conduct much worse.
