The correct answer is E
Explanation
The fovea lies slightly below and to one side of the optic disk. It is found in the centre of a shallow depression or pit (the macula). Only cones are present at the fovea, which is an area approximately 0.2 mm in diameter: all other parts of the retina including blood vessels are pushed aside. The cones here have individual connections with the bipolar and ganglion cells, hence the fovea gives us our most sensitive and acute vision.

yes its E fovea. THe site on the retina where visual acuity is highest is is the fovea centralis, a small depression at the center of a yellowish area ,the macula lutea.REtina in fovea centralis (diameter 5mm)is particualarly thin at this site and contains the largest concentration of cone cells.
