A star that has an apparent magnitude of 0 (see Fig. 11-2, Comins and Kaufmann, Discovering the Universe, 7th Ed.)
A)   would be fainter than Spica (alpha Virginis), which has an apparent magnitude of +1.0.
B)   would be brighter than Deneb (alpha Cygni), which has an apparent magnitude of +1.2.
C)   would have infinite brightness, since 1/0 = infinity.
D)   would not be emitting any light, and therefore could not be seen from the Earth.
