Solution

The correct option is C Rhodopsin
Rhodopsin, also known as visual purple, is a light-sensitive receptor protein. It is a biological pigment in photoreceptor cells of the retina.
Rhodopsin is the primary pigment found in rod photoreceptors. Rhodopsins belong to the G-protein-coupled receptor (GPCR) family. This protein is necessary for normal vision, particularly in low-light conditions. It allows night vision and is extremely sensitive to light. Exposed to a spectrum of light, the pigment immediately bleaches, and it takes about 30 minutes to regenerate fully, but most of the adaptation occurs within the first five or ten minutes in the dark.
