The correct statement is:
**The light is emitted as excited electrons fall into lower energy states.**
In a neon sign, when an electric current excites the neon gas, electrons are energized to higher energy levels. When these electrons fall back to their original lower energy states, they release energy in the form of light. The other statements are not accurate regarding the properties of neon and the light it emits.
