Detailed explanation-1: -Expert-Verified Answer. Answer: Option D) protostar, main-sequence star, a red supergiant, nebula, supernova, neutron star, or black hole is the correct option.
Detailed explanation-2: -Depending on its size, the star becomes either an average star or a massive star. The average star then becomes a red giant, a planetary nebula, and ends its life as a white dwarf. The massive star turns into a red supergiant, goes supernova, and ends up as a neutron star or a black hole-again, depending on its size.
Detailed explanation-3: -However, their life cycles start to differ after the red giant phase. A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star.
