    The correct answer is D. optic disc.

    The optic disc is the area in the back of the eye where the optic nerve exits and blood vessels enter and exit the eye. This area does not contain any photoreceptor cells, which are responsible for sensing light and sending visual signals to the brain. Therefore, anything that falls on the optic disc cannot be seen by the brain, leading to a "blind spot" in our visual field. This blind spot is not usually noticeable because the brain compensates for it by filling in the missing information from the surrounding visual field.
