Interposition refers to the fact that when one object partially covers another, it appears closer to the viewer. This is a important depth cue used by the brain to estimate distance and depth perception. Option A, Blocking is not a cue, it is just an effect of one object blocking the view of another. Option B, The principle of occlusion is a more general term that involves any object being blocked or covered by another object. Option D, Interpenetration refers to objects that are partially inside of one another, and is not related to distance perception.
