Which of the following is an example of a monocular cue for depth perception?

Linear perspective is a powerful monocular cue for depth perception. It involves the perception of depth that arises from the way parallel lines appear to converge as they recede into the distance. This phenomenon is observable in various contexts, such as viewing long roads or railway tracks that seem to meet at a distant point on the horizon. The brain uses this visual information to gauge how far away objects are, allowing us to construct a three-dimensional understanding of our environment from just one eye's perspective.

Other depth cues like retinal disparity and convergence rely on binocular vision, meaning they require information from both eyes to create depth perception. In contrast, monocular cues, such as linear perspective, can be perceived effectively with just one eye, making them particularly useful in various visual contexts. Clairvoyance, which refers to the claimed ability to gain information through extrasensory perception, is not associated with depth perception and does not belong to the discussed categories.
