is the characteristic color bands that represent the range of radiations emitted by an element when it is heated

Emission spectrum

Explanation:

The emmison spectrum is unique to every elements

Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light.

The color band indicate the amount of energy emitted in form of electromagnetic radiation.

When electrons in an atom gain energy, the become excited, on falling and losing their energy, they return to their ground state releasing the measure of energy they absorbed in transitioning.

whichever one it is, it's definitely not one that you included on the list you provided.
