O the color that is produced
O the energy that is released
O the amount of gravity that is present
O the types of elements that are present

b

Explanation:

The answer is B) the energy that is released

Explanation:

Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.

Hope this helps!
