The Progenitor of SN 1987A Was a Smaller Blue Supergiant

The progenitor of SN 1987A was a smaller blue supergiant rather than a larger red supergiant when the core erupted as a supernova. What difference did this make?

A) Blue indicates a hotter surface temperature. Thus, this was a brighter supernova than it would have been if the progenitor had been a red supergiant.
B) Blue supergiants are inherently more massive and more compact than red supergiants. Thus, this was a brighter supernova than it would have been if the progenitor had been a red supergiant.
C) The more compact state of the blue supernova meant that more energy was required to lift the outer layers away from the core, and thus, less energy remained to increase the luminosity.
D) Blue supergiants are younger than red supergiants. Thus, fewer metals had been formed in the supergiant, and the resulting supernova remnant contained fewer metals than it would have had it erupted while a red supernova.
