Maximum visual acuity in retina is present on 
Select and explain. 
A. Optic disc, B. Fovea centralis, C. Macula lutea, D. Peripheral part
B: Fovea centralis
Answer: B: Fovea centralis 
Explanation: (B) Fovea centralis > Visual acuity, or resolving power, is the property of cones. To resolve detail, the eye's optical system has to project a focused image on the fovea, a region inside the macula having the highest density of cone photoreceptor cells (the only kind of photoreceptors existing on the fovea), thus having the highest resolution and best color vision.
