Solution
The correct option is B Corpora quadrigemina
Corpora quadrigemina are the four round swellings or lobes which are present in the dorsal part of the midbrain. They are not a part of the eye.
Fovea is the central pit of the yellowish pigmented spot called macula lutea present at the posterior pole of the eye lateral to the blind spot. The visual acuity is the greatest at fovea centralis.
The blind spot is that region of the eye where there are no photoreceptor cells present.
The pupil is the aperture present in the centre of the iris, which is the coloured portion of the eye. The pupil allows the light to reach the retina. Its diameter is regulated by the iris.
