Superconductors are substances which A. conduct electricity at low temperature B. offer high resistance to the flow of current C. offer no resistance to the flow of electricity D. conduct electricity at high temperatures

The correct answer is: C. offer no resistance to the flow of electricity.

Superconductors are materials that conduct electricity with no resistance. This means that a current can flow through a superconductor without any loss of energy. Superconductors are made of materials that have been cooled to very low temperatures. When a superconductor is cooled to its critical temperature, it loses all resistance to the flow of electricity. This makes superconductors very useful for applications where electricity needs to be transmitted without loss of energy.

Option A is incorrect because superconductors conduct electricity
