Photoreceptors are mostly densely packed in:

A) the fovea.
B) peripheral vision.
C) the retina.
D) the optic disc.

Fovea

Central region of the retina specialized for high visual acuity; its receptive fields are at the center of the eye’s visual field.

Photoreceptors

Cells in the retina that are sensitive to light and enable the process of converting light into electrical signals for vision.
