Super Giants and above normally go through a Super Nova stage on the way to their death yes.
Not exactly. Red giants become white dwarf stars. It is the red supergiants that can become supernovas.
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
No. Supernovas are cataclysmic eruptions from massive stars that have come to the end of their lives. See related questions
A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.

D. white dwarfs. Most stars in the Milky Way, including our Sun, will eventually end their lives as white dwarfs. This occurs after the star has exhausted its nuclear fuel and shed its outer layers.

Red giants - As they near the end of their life they will "shed" their outer layers, returning material back into the Universe as a planetary nebula.Supernova - they seed the Universe with heavy elements - metallicity, which when formed into "newer" stars has the effect of making them "burn" slower.Supernova are also one manner in which dust clouds get that "nudge" to start forming protostars.
