How does a star become a red giant?

• A star becomes a red giant by fusing helium into carbon in its core.

• A star becomes a red giant by gaining mass from a nearby star.

• A star becomes a red giant by exhausting hydrogen fuel, causing core contraction and outer layer expansion.

• A star becomes a red giant by cooling down and shrinking in size.

What happens to a star after it becomes a supernova?

• A star becomes a planet after a supernova.

• A star simply fades away without any change.

• A star becomes a neutron star or a black hole after a supernova.
