A) Fovea centralis
B) Retina
C) Fossa ovalis
D) Blind spots
Correct Answer: A
Solution :

Hence, this pan is called yellow spot or macula lutea. Fovea centralis is a small depression in the centre of macula lutea in which cones are most densely concentrated. So fovea centralis is the area of sharpest vision.
