Which lists types of materials from most conductive to least conductive?
a. insulator, semiconductor, conductor, superconductor
b. superconductor, conductor, semiconductor, insulator
c. conductor, insulator, semiconductor, superconductor
d. semiconductor, conductor, superconductor, insulator

The correct answer is B) Superconductor, conductor, semiconductor, insulator.

Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.

Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.

Thus, B) is the right answer.
