Answer:
b. is made of superheated gas.
Explanation:
Most atoms in the Sun exist as plasma, or a fourth state of matter made up of superheated gas with an electrical charge which is both positive as well as negative. Our Sun consists almost entirely of the elements hydrogen and helium. ... The core is plasma, but moves similarly to a gas. Its temperature is around 27 million degrees Celsius. And because the Sun is not solid, it does not have a defined outer boundary.
Hope this helps!!
