Lateral inhibition through horizontal cells in the mammalian retina improves visual contrast.
Retinal lateral inhibition (RLI) exists even comprehended as a contrast encoder. RLI produces a stimulation difference authorizing increased sensory perception and improves the contrast between the center and the periphery in a stimulated region.
Lateral inhibition causes neurons better sensitive to spatially altering stimulus than to spatially uniform stimulus. This exists because a neuron getting produced by a spatially uniform stimulus exists also inhibited by its surrounding neurons, therefore suppressing its response.
Lateral inhibition improves the difference and sharpness in visual reaction. This phenomenon already appears in the mammalian retina. In the dark, a small light stimulus will improve the various photoreceptors (rod cells).
Therefore, the correct answer is option B. enhances visual contrast.
