According to corollary discharge theory, when we move our eyes, there is a signal sent to the brain called corollary discharge. This signal predicts the visual consequences of the eye movement. In this case, the corollary discharge predicts that the image of the man sitting in the chair will move to the right because of the eye movement. However, because the input from the image-retina system (the actual image of the man on the retina) and the eye-head system (the predicted image of the man based on the corollary discharge) are the same, we perceive the man as stationary. Therefore, choice A is the correct answer.
