When your psychology professor is lecturing to your class,your professor can tell which students are sitting in the first,second,third,etc.,row,in part because students in the closer rows obstruct his or her view of students in more distant rows.Which depth cue does this illustrate

A)  texture gradient
B)  relative size 
C)  interposition
D)  linear perspective

Interposition

A visual cue that allows us to perceive the depth by understanding that if one object partly blocks another, the blocking object is closer to the observer.

Texture Gradient

A visual cue used to perceive depth, where the texture of a surface appears denser as the distance from the observer increases.

Relative Size

A perceptual clue that allows the observation of the size of an object in relation to other objects in its surrounding, contributing to the perception of depth.
