An AGN is emitting with a luminosity of 2×1040W. The AGN's brightness varies by 10% on a time scale of 20 hours. Assuming that the size of the emitting region of the AGN is three Schwarzschild radii, choose which of the following values could give the mass of the central Black Hole, in solar masses.
