Which outcome results when electrons populate the conduction band?

A)Material transitions to conductive state
B)Phonon scattering decreases rapidly
C)Ferromagnetic domains become stable
D)Cooper pair formation accelerates rapidly

💡 Explanation

A conductive state emerges with available electrons in the conduction band because electron mobility is enhanced by decreased resistance from the now-available energy states. Therefore, conductivity increases; rather than other phenomena such as increased phonon scattering which impedes conductivity.
