We can use the formula E = hc/λ, where E is the energy of the photon, h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon. Rearranging the formula, we get λ = hc/E.

Substituting the given values, we get λ = (6.63 × 10^-34 J·s) × (3.00 × 10^8 m/s) / 11.7 × 10^-9 J = 0.457 nm. Therefore, the answer is C.
