Although often hundreds of millions of times more massive than the black holes produced by the deaths of individual stars, the supermassive black holes astronomers find in the centers of galaxies are "less extreme" than their lower-mass counterparts in one respect:
A. They exhibit finite time dilation at their event horizon.
B. They exhibit a much reduced gravitational redshift at their event horizon.
C. They are much smaller in size.
D. They are expected to evaporate much sooner.
E. They exhibit much weaker tidal forces near their event horizon.
