Which of the following stars are/is likely to supernova at some point in it(s) life cycle?
Just Rigel because this star has the high mass needed
No, Vega is not likely to explode as a supernova. With a mass only about 2.1 times that of our Sun, Vega does not meet the high-mass requirements (typically solar masses) needed to produce a supernova. It will instead evolve into a red giant and eventually become a white dwarf.
