Step 1: Superconductivity Defined.
Superconductivity is the state where specific materials, at temperatures below a critical point, display absolute zero electrical resistance. This defining characteristic enables superconductors to transmit electricity with perfect efficiency, incurring no energy dissipation.
Step 2: Inferred Answer.
Consequently, the definitive response is that superconductors possess zero electrical resistance below their critical temperature, aligning with option (1).
