C. longest wavelength
Explanation:
Photons with the lowest energy have the longest wavelength and the shortest frequency.
The energy of photons is given as:
E = hf =
where f is the frequency of photon
h is the planck's constant
∧ is wavelength
c is the speed of light
The more the frequency, the higher the energy of the photon.
Photons with low energy have long wavelength.
