Why are people generally unable to distinguish color in their extreme peripheral vision?

A) Receptors in the periphery are mostly rods.
B) Receptors in the periphery are too close to the blind spot.
C) Yellow pigments in the periphery filter out many wavelengths.
D) Colored light is diffracted by the eyeball like a rainbow so it does not reach the periphery.

Peripheral Vision

The area of visual perception that occurs outside the central area of focus, allowing one to see objects that are not in the direct line of sight.

Receptors

Specialized cells or proteins in the body that detect and respond to specific substances, such as hormones, neurotransmitters, or environmental stimuli.

Rods

Photoreceptor cells in the retina of the eye responsible for vision at low light levels, but not color detection.
