To start from the beginning, a stars "fuel" is initially H, or hydrogen the lightest element. A star is basically a nuclear reactor and fuses the H molecules together to form He or helium (this process is called fusion) depending on the size of the star, it can fuse heavier and heavier elements and if you have a really big star it will make iron from fusion or a little star will burn out extremely slowly and make a brown dwarf. A big star could do a lot of things. It could go supernova and eventually form a black hole or it could become a quasar, to a few other things.
A star can become a white dwarf, a neutron star or a black hole. That depends on its mass.
Stars like the Sun will become white dwarf stars.
If the star has about 8 times or more of our Sun's mass it will become a neutron star or black hole, after exploding as a supernova.
It will become a black hole if the remnant of the star after the supernova
has at least 3 times the mass of the Sun.
It's as simple as that. If you want to know HOW it becomes a neutron star or black hole go to http://www.pbs.org/wgbh/nova/blackhole/form-flash.html
That depends on the mass of the star in question. Most stars become Red Giants when they run low on Hydrogen fuel. Sun-like stars eventually become Planetary nebulae, caused by an explosion that throws out star material into space. After this, they eventually become white dwarfs, which are effectively dead stars. They are extremely hot and small. Larger stars undergo Supernova explosions, after which they either become neutron stars or black holes.
It turns into a white dwarf star, a neutron star or a black hole.
Black hole.
Comment: I think a black hole is something such a star can become, depending on its mass.
I'm unsure what the correct answer is meant to be.
white dwarf a black dwarf
it becomes a white dwarf and a supernova
A white dwarf
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
runs out of fuel to fuse
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
After the sun runs out of fuel is will become a white dwarf, a neutron star, or a black hole.
When a Star runs out of fuel, it will expand into what is known as a "Red Giant". Massive stars will become "Red Supergiants". This phase will last until the star exhausts its remaining fuel. At this point, the pressure of the nuclear reaction is not strong enough to equalize the force of gravity and the star will collapse. Go to related link to read more about Stars... ;)

A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
a dwarf star
A neutron star is already the remains of a massive star that has run out of fuel.
When the star runs out of fuel. Most stars burn (fuse, actually) hydrogen. When this runs out, what happens next depends on the mass of the star... heavier stars can fuse heavier elements for a short time, but lower mass stars simply collapse into white dwarfs.
Usually the fact that the star runs out of fuel.
It collapses.
helium
runs out of fuel to fuse
we would die
It will implode and depending on its size it will become a white dwarf, go nova, supernova. Extremely larger will form a black hole. .
