Solution

The correct option is A

Fovea centralis


The retina is the neural and sensory layer of the eyeball. A small oval, a yellow area of the retina lying exactly opposite the centre of the cornea is named macula lutea or yellow spot which has in its middle a shallow depression called the fovea contrails, which contains only cones. The ability of detailed vision is highest in the fovea.
