The BCS theory of superconductivity details the working of a superconductor. Choose the statement below that describes one of its characteristics

a. Single electrons are responsible for establishing currents in the superconductor. b. Currents flow without resistance until the lattice begins to vibrate. c. The repulsion of electrons in pairs is significantly reduced by the extremely low temperatures of superconductor operation, making electron pairing possible. d. A pair of electrons becomes like a boson and transitions to a ground state with other electron pairs.

e. The resistance decreases in proportion to the lattice vibrations, which in turn decrease with decreasing temperature.
