Which of the following is a monocular depth cue that is absent in pictorial representation but present in real life?

A) linear perspective
B) relative size
C) interposition
D) motion parallax

Motion parallax is a monocular depth cue that involves the perception of relative motion of objects in the visual field that occurs when the observer moves their head or body. This cue is absent in pictorial representations such as photographs or paintings, as the image is static and does not change with movement. However, in real life, an observer can use motion parallax to estimate the distance of objects in the environment. Linear perspective, relative size, and interposition are all pictorial depth cues that can be represented in two-dimensional images.
