Answer:
Plasma state
Explanation:
Nitrogen and oxygen in their gaseous stage are considered as insulator as they are not able to pass electricity through them. Electricity can be conducted through a medium when electrons move.
Hence, when both nitrogen and oxygen are in plasma state they conduct electricity. A plasma state of a gas is the state in which it exists in ionized state where electrons are able to move freely.
hence , Plasma state is correct.
