Solution

In superconductivity, the resistivity of a material becomes zero. This phenomenon occurs below a certain critical temperature specific to each superconducting material. At this temperature, the material enters a superconducting state where it can conduct electricity without any energy loss due to resistance.

The transition to superconductivity is characterized by the formation of Cooper pairs, where electrons couple together at low temperatures, allowing them to move through the lattice of the material without scattering. This results in the expulsion of magnetic fields from the superconductor, a phenomenon known as the Meissner effect. Therefore, the correct answer is that the resistivity of a material becomes zero in the superconducting state.

Thus, the answer is Zero.
