Answer:
B. Become a white dwarf star.
Explanation:
As the Sun is a medium size star in mid of its life of around 10 Billion years. When it will exhaust all the Hydrogen in the core, it will go through a long process of death: Converting into a red giant to Planetary Nebula to a white dwarf. It will spend trilliion of years in white dwarf phase before fading and converting to a Black dwarf.
If it had been a massive star it would have made a Supernova and then ultimately a black hole or a neutron star.
