The first step in the process of photoreception is the absorption of a photon by a visual pigment (Option b).
The process of photoreception makes reference to all phenomena that occur from photoreceptor cells in the eye being excited as a consequence of an environmental visual stimulus until the processing of the image in the brain.
Therefore, with this data, we can see that the process of photoreception is initiated by the stimulation of photoreceptor cells in the eye, which contain pigments that serve to sense photon signals.
