Answer and Step-by-step explanation:
<u>C and D is the answer.</u>
It needs a lot of mass so that it can collapse on itself to form a black hole, and when it dies, it also collapses on itself, forming a black hole.
A is incorrect because the mass of our sun hasn't made it to collapse, and it still has some billions of years before the mass increases.
B is incorrect because the hydrogen needs to be depleted in order for the sun/star to start the nuclear process.
