Final answer:
Most retinal cones are concentrated in the fovea, the central pit in the retina that contains the highest density of cones.
Step-by-step explanation:
Most retinal cones, which are responsible for color vision and high visual acuity, are concentrated in the fovea. The fovea is a small central pit in the retina that contains the highest density of cones. It is responsible for detailed vision and is essential for activities such as reading, recognizing faces, and other tasks that require sharp, focused vision.
