It's hard to find a table of conductivity of metals in a physics textbook, but many list values of resistivity, ρ, for at least a few metals. Remember resistivity is the inverse of conductivity (a more resistive material will be less conductive.)
Copper has one of the lowest resistivities (1.47×10−8 Ω·m)—it's a very good conductor. B is incorrect.
Which of the following materials is the poorest electrical conductor?
