Which of the following is the best answer to the question "Will our sun become a black hole?"

• Our sun's mass just right to create a black hole. As a high mass star it will explode in a supernova and then a collapse into a black hole

• Our sun's mass is too high to create a black hole. As a high mass star it will explode in a supernova and then a white dwarf

• Our sun's mass is too low to create a black hole. As a medium mass star it will expand into a planetary nebula and then a white dwarf

• Our sun's mass is too low to create a black hole. As a low mass star it will collapse into a blue dwarf and then further into a red dwarf
