<em>The answer is (A). Motion parallax is detected because we perceive binocular disparity.</em>
Explanation:
<em>Motion parallax: The term parallax refers to a position change.Motion parallax is a monocular depth cue coming from the velocities of relative objects passing across a moving person's retinae. </em>
<em>Therefore, the motion parallax is a position change that is caused by the movement of the viewer or person.</em>
A. Motion Parallax is detected because we perceive binocular disparity. The depth perception is the ability to see the world in three dimensions. It arises from a variety of depth cues like the binocular and monocular cues. In binocular cues, it includes disparity and yielding depth from binocular vision through exploitation of parallax.
