Answer:
1.black dwarf
H.white dwarf
A.Red giant
B.Main sequence
C.Nebula
D.Stellar nursey
Explanation:
On the last part where the main sequence happens, it really depends on the mass of the star using the sun as an example, our sun has a low mass meaning when it close to its dying form it would go to Planetary Nebula then collaspe as a white dwarf. When a massive star goes through the main sequence and it reaches its dying form, with the high mass it'll also die as a white drawf when it has very high mass it'll possibly end up as a black hole.
Hope this helps, sorry if it doesn't!
