The correct option is A Rhodopsin
Vitamin A is required for the formation of the photoreceptor rhodopsin, which is a complex of retinal and the vision protein opsin, where retinal functions as the chromophore. Rhodopsins are found in animals and green algae where they act as regulators of light-activated photochannels and in archae where they act as light-driven in pumps.
Therefore, the correct answer is option A.
