Solution

The correct option is D Rods and cones are absent
The blind spot is the region in the posterior part of the eye. There are no photoreceptor cells, rods and cone cells are absent in this region.
The rods and the cones are the cells that can detect light and help in the formation of the image.
As the light cannot be detected, there is no image formation at this spot.
Thus, the correct answer is option C.
