The correct answer is plasma.
When the temperature of a gas is very high, as it is, in extremely hot objects such as stars such as Sun,or incandescent or discharge lamps such as Neon lights, the gas exists in an ionized state.
At high temperatures, electrons gain enough energy to escape the attractive forces of the nucleus. When the electrons leave the atom, the atom becomes positively charged and these charged atoms are called ions.
At high temperatures, the matter can also contain neutrons which are neutral particles and are the constituents of the nucleus.
Thus the state at which matter can exist as ions, electrons, protons or neutrons is called plasma.
