How does the diameter of a black hole (size of the event horizon)depend on the mass inside the black hole?
A) The greater the mass,the smaller the diameter.
B) The greater the mass,the greater the diameter up to the mass limit for a black hole;above that mass,the black hole collapses.
C) The diameter does not depend on the mass.
D) The greater the mass,the greater the diameter.

According to the formula for the Schwarzschild radius (which gives the size of the event horizon of a non-rotating black hole), the radius (and hence, the diameter) is directly proportional to the mass of the black hole. Therefore, the greater the mass, the greater the diameter of the black hole.
