Final answer:
The size constancy phenomenon allows us to perceive objects as the same size even when the retinal image changes.
Step-by-step explanation:
The correct answer is (C) Size constancy.
Size constancy is the perceptual phenomenon that allows us to perceive objects as being the same size even when the retinal image of the object changes.
When a car drives away, the retinal image of the car on your retina becomes smaller.
However, your brain uses cues such as the known size of the car and its distance from you to perceive the car as remaining the same size. This is an example of size constancy.
