Answer 1

C. Each human eye has a different view of the same image.

Retinal disparity is created because each eye has a slightly different viewpoint of the same scene due to their different positions on the head. The brain uses the difference in the images of an object projected onto the retinas of the two eyes to calculate the distance of an object and perceive depth.
