Solution

The correct option is C Dissociation of the retinal from opsin
Dissociation of retinal from opsin results in the generation of potential difference. When light is absorbed by rhodopsin, retinal is split from protein and the rod becomes partially bleached. At the same time nerve impulse is generated, which takes the information about the image to the brain.
