Answer:

The star must be 10 to 28 times larger than Earth’s sun, and a supernova explosion must have occurred.

Option: (A)

Explanation:
According to NASA, for a star to get converted into a black hole, it needs to be as big as 20 times the Earth's Sun.

That being the primary requirement, it also needs to 'collapse' into itself once the fuel in the star gets over.

To support the process, there also has to be a 'supernova explosion' that sends the matter of the star into the nearby space.
