The energy of a photon can be calculated using the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Substituting the given values, we get E = (6.626 x 10^-34 J s) x (3.00 x 10^8 m/s) / (656 x 10^-9 m) = 3.03 x 10^-19 J. Therefore, option B is the correct answer.
