Question

what causes a star to shine brightly?
○ the color that is produced
○ the energy that is released
○ the amount of gravity that is present
○ the types of elements that are present

Explanation:

Stars shine brightly due to nuclear fusion in their cores, which releases a large amount of energy (in the form of light and heat). The color of a star is related to its temperature, gravity affects its structure but not direct shining, and elements are involved in fusion but the key is the energy released from fusion. So the correct option is the one about energy release.

Answer:

B. the energy that is released
