State of matter

Explanation:

State of matter is not a physical property used by scientists to classify stars because all stars are made up of gases.

The gases can become furnished with excessive heat and they become ionized to plasma state of matter. All stars are gas giants and with some plasma.

The correct answer is: state of matter.

Explanation:

When classifying stars, scientists use different criteria,  as, for example: color, temperature, size, composition, and brightness. On the other hand, state of matter is not a physical property which is taken into account by scientist to classify stars, as it is not one of the star's characteristics.
