Correct Answer

Explanation

Gases can conduct electricity under certain conditions, such as when they are ionized or when they contain free-moving charged particles. This can occur in the presence of high temperatures, high voltages, or when the gas is subjected to a strong electric field. In these cases, the gas molecules can become ionized, meaning they lose or gain electrons, creating charged particles called ions. These ions can then move freely within the gas, allowing it to conduct electricity.
