The energy of a photon can be calculated using the formula E = hf, where h is Planck's constant (6.626 x 10^-34 J*s) and f is the frequency of the photon. Plugging in the given values, we get E = (6.626 x 10^-34 J*s)(6.0 x 10^10 Hz) = 3.98 x 10^-23 J, which is equivalent to 3.98 x 10^9 pJ or 3.98 x 10^6 nJ. Option C matches this value in Joules.
