Why do metals tend to be good conductors of electric current?

A.Metals have more negative charges than positive charges, which produces electric currents.

B.The force of attraction between metal ions and electrons is very weak, causing electrons to flow out of the metal.

C.Valence electrons of metals are very mobile and can carry electric current through the metal.

D.Cations and anions in the metal easily move in opposite directions, carrying electric current
