Answer:
B). Binocular.
Step-by-step explanation:
'Binocular disparity' is demonstrated as the discrepancy which is caused due to the variation or distinction among the retinal images formed in our left and right eyes and the polarity of signals that leads to influence the actual image or picture formed by our brain(due to variation in signals). These two images are instinctively collated by our brain in order to perceive depth information as in case of both the images being similar, both are combined together in order to provide a significant signal to perceive depth. This disparity is popularly known as 'binocular disparity'.
