The pigment necessary for night vision is:
A) rods.
B) cones.
C) rhodopsin.
D) fovea centralis.
Rhodopsin
A pigment found in the rods of the retina that is responsible for the first step in the perception of light.
Rods
Photoreceptor cells in the retina of the eye that are sensitive to low light and contribute to night vision.
Cones
Photoreceptor cells in the retina of the eye that function best in relatively bright light and enable color vision.

Final Answer :
C
Explanation :
Rhodopsin is a pigment found in the rod cells of the retina that is necessary for night vision. When light enters the eye, it combines with rhodopsin to produce a chemical reaction that signals the brain to interpret the images. The other choices (rods, cones, fovea centralis) are all parts of the retina but do not specifically relate to the pigment necessary for night vision.
