C) shape constancy.
D) linear perspective.

Question

This situation illustrates shape constancy, which is the ability to perceive an object as maintaining its shape despite changes in its orientation or size. Even though the door's image on our retinas becomes trapezoidal as it opens, we still perceive it as rectangular because our brains use prior knowledge and expectations about the door's shape to maintain a consistent perception of it. Retinal disparity involves the differences between the images on our two retinas, interposition involves the partial blocking of one object by another, and linear perspective involves the apparent convergence of parallel lines in the distance. None of these concepts fully explain the situation described.
