Answer & Solution
Correct Answer:
Option
D
Super conductivity is a phenomenon in which the resistance of a substance becomes zero at very low temperature. Superconductors are solids that at low temperatures exhibit zero resistance to the flow of electrical current, a phenomenon known as superconductivity. The temperature at which the electrical resistance of a substance drops to zero is its superconducting transition temperature (T c).
