Solution
The correct option is C Fovea
The point of exit of optic nerve from eye forms a “blind spot” in the retina which is devoid of both rods and cones and hence no image is formed on it. Rods and cones are the secondary photoreceptors that are presently buried under the layer of blood vessels and nerve fibers throughout the retina. Rod cells are mostly concentrated near the edges of retina while densely packed cones are present in the fovea. The choroid is a dark pigmented thin vascular layer and is characterized by the presence of many blood vessels but no cones and rods.
So, the correct answer is option C.
