Answer:
feature detectors
Explanation:
Physiologically, Receptors are organ or cell that are able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve.
Dendrite are branch-like segments located at the anterior part of a neurone that function in receiving stimulation via electrical messages in order for the cell to become active.
Retinal cells also known as photoreceptor cell works in the area of light detection. They usually take light focused by the cornea and lens and convert it into chemical and nervous signals which are transported to visual centers in the brain by way of the optic nerve.
Feature detectors refers to the way by which the nervous system filters complex natural stimuli with the use of neurone in order to extract behaviorally qualities (such as orientation, movement, and length) that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant and unimportant background or noise.
Therefore, from the above explanation; Option d is the right choice.
