<h2>Answer: free electrons</h2>

<u>Plasma</u> is known as the 4th state of matter and is itself ionized gas. In this sense, ionization consists of the production of ions, which are <u>electrically charged atoms or molecules due to</u><u> the excess or lack of electrons</u><u> with respect to a neutral atom or molecule. </u>

That is why in this process there are always<u> free electrons</u>. Therefore in heating gas to create plasma can yield  free electrons, and the correct option is D.
