- D.
From white dwarfs
Correct Answer
A. From the collapse of massive starsExplanation
Stellar black holes are formed from the gravitational collapse of massive stars at the end of their life cycles. Stellar black holes are created when massive stars undergo a supernova explosion, and their cores collapse under gravity's relentless pull. These black holes possess an event horizon beyond which nothing escapes, even light. Their size and mass vary, typically ranging from a few to around 20 times that of the Sun.Rate this question:
