Answer 1

Answer:

I think option C

nebula , protostar , main sequence star , red super gaint , supernova , neutron star or black hole

hope it may helps you

Answer 2

Answer:

Option D) protostar, main-sequence star, a red supergiant, nebula, supernova, neutron star, or black hole is the correct option.

Explanation:

The life cycle of a high-mass star is can be seen in the order of protostar, main-sequence star, a red supergiant, nebula, supernova, neutron star, or black hole.

• Protostars- are the warm clump of molecules formed when the gas particles present in the existing molecular cloud run into each other producing heat energy. Infrared vision can be used to see them.
• main-sequence star- It is formed when the fusion occurs due to an increase in core temperature. It is an exothermic reaction. Hydrogen atoms are converted into helium atoms in this process.
• Red supergiant star is formed when the conversion of hydrogen into helium stops and the star contracts inwards through gravity and expansion takes place, during expansion it transforms into a subgiant star and then into a red supergiant star.
• Nebula is formed when the core is collapsed again after the fusion of helium into carbon and the outer layers of the star are expelled, and a planetary nebula is formed by the outer layers.
• Supernova is formed when the helium fusion ends and iron appears at the core causing the core to collapse again as the fusion of iron absorbs energy.
• Blackhole or neutron star is formed by the core of the star when most of the star material is blasted or expelled into the space
