Correct Answer: superconductor


Solution : The correct option is a superconductor.

At low temperatures of 7.2 Kelvin, lead exhibits phase transitions towards superconductivity. In 1913, this finding was made. Lead's electrical resistivity falls to zero at this temperature, sometimes referred to as the critical temperature. The transition is so abrupt and complete that it seems to be a change in the state of matter.
