When star A runs out of fuel, it explodes in a supernova and becomes a neutron star. When star B runs out of fuel, it contracts to become a white dwarf. Based on this information which of the following conclusions is most likely true:
A. Star A had a larger mass than star B
B. For most of its life cycle, star A appeared substantially brighter than star B from earth
C. For most of its life cycle, star B appeared substantially brighter than star A from earth
