Superconductors are substances which:

  1. A
    conduct electricity at lower temperature.
  2. B
    offer high resistance to the flow of currrent.
  3. C
    offer no resistance to the flow of current.
  4. D
    conduct electricity at high temperature.

Solution & Step-by-step Explanation

Superconductors are unique materials that undergo a dramatic quantum phase shift below a specific critical transition temperature, after which they offer zero or no resistance to the flow of electric current and expel internal magnetic fields.
