How does the diameter of a black hole (size of the event horizon) depend on the mass inside the black hole?
A) The diameter does not depend on the mass.
B) The greater the mass, the greater is the diameter-until the mass becomes relatively large and then the diameter decreases with increasing mass.
C) The greater the mass, the greater is the diameter.
D) The greater the mass, the smaller is the diameter.

The diameter of a black hole, or the size of its event horizon, increases linearly with its mass. This relationship is described by the Schwarzschild radius formula, which directly ties the radius (and thus the diameter) of the event horizon to the mass of the black hole.
