Air is primarily composed of Nitrogen and oxygen gases. Which state of these gases can conduct electricity?

Nitrogen and oxygen gas can conduct electricity in their molten or fused state.

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.
