1 points
gmc, planetary nebula, protostar, pre - main - sequence star, main sequence star, giant star, multiple - shell - burning giant star/supergiant star, supernova, black hole
protostar, pre - main - sequence star, main sequence star, giant star, horizontal branch star, double shell - burning giant star, planetary nebula, supernova, neutron star, gmc
gmc, protostar, pre - main - sequence star, main sequence star, giant star, helium flash, horizontal branch star, double shell - burning giant star, planetary nebula, white dwarf star, neutron star
gmc, protostar, pre main - sequence star, main sequence star, giant star, horizontal branch star, several phases of multiple - shell burning giant star/supergiant, supernova, black hole

Explanation:

A star with a mass around 50 M☉ starts as a Giant Molecular Cloud (GMC). It then collapses to form a protostar, evolves to a pre - main - sequence star, and then to a main - sequence star. After exhausting hydrogen in the core, it becomes a giant star or supergiant. It goes through multiple phases of multiple - shell burning, then undergoes a supernova explosion. For a star of this mass, the remnant is a black hole.

Answer:

D. GMC, Protostar, Pre - main - sequence star, Main sequence star, Giant star, Horizontal Branch star, Several phases of multiple - shell burning giant star/Supergiant, Supernova, Black hole
