From "The case of the missing neutrino" by John Gribbon, written in

worlds" by Michio Kaku, written in 2005, our sun would turn into a red
giant after death.

Which one is correct? Or are both cases possible? Or white dwarf was a
previous theory while red giant is a more recent one?

Gribbon is correct - the Sun will become a white dwarf after death.
However it will become a red giant while dying. Its red giant phase
will be fairly brief, perhaps a few million years. The final white
dwarf phase will last many billion years.
