What kind of star is most likely to become a white-dwarf supernova? A. a star like our Sun B. a white dwarf star with a red giant binary companion C. a pulsar D. an O star Is the answer B? For D, as the surface temperature of a star would change over time so spectral type cannot tell us about the fate of the stars?
