Which of these properties of a star best determines whether it would end up as a white dwarf, neutron star, or black hole?
mass
density
brightness
temperature

The correct answer to the question is : Mass i.e mass is the property that determines the formation of black hole,neutron star or white dwarf after the end of a star.

EXPLANATION:

Before going to answer this question, first we have to understand Chandrasekhar limit.

It is the Chandrasekhar limit which gives an idea about the formation of white dwarf, neutron star, or black hole at the last stage of a dying star.

The Chandrasekhar limit is equal to 1.4 solar masses.

As per Chandrasekhar limit, if the mass of the dying star is less than 1.4 solar mass, then it will become a white dwarf.

If the mass of the dying star is greater than 1.4 solar mass, then a neutron star or black hole is formed.

Hence, the correct answer of this question is mass.

answer would be d.) i hope this

explanation:

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
