We can use the equation E = hν, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J.s), and ν is the frequency of the photon.
Rearranging the equation, we get ν = E/h.
Substituting the given values, we get:
ν = (4.38 x 10^-18 J) / (6.626 x 10^-34 J.s)
ν = 6.61 x 10^15 s^-1 or Hz.
Therefore, the frequency of the photon is 6.61 x 10^15 Hz or 6.61 x 10^15 s^-1.
The best choice is B.
