The energy of a photon can be calculated using the formula: E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photon.

Plugging in the values for hydrogen's 434 nm spectral line, we get:

E = (6.626 x 10^-34 J s) x (3 x 10^8 m/s) / (434 x 10^-9 m) 
E = 4.58 x 10^-19 J

Therefore, the correct answer is D.
