The correct answer of this question is : Black hole
EXPLANATION :
As per the question, the star is formed from the large nebula. The star which has formed from large nebula due to the gravitational pull might have masses greater than 3.5 solar masses.
At the end of the star i.e when it is run out of its fuel, it will be converted into black hole as per Chandrasekhar limit which depicts that a dying star will be a black hole if its mass is greater than 3.5 solar masses.
Hence, the correct answer is black hole.
