B) accommodation
C) stereopsis?
D) motion parallax

Question

Perspective convergence is the depth cue that is most important in the Ponzo illusion, where parallel lines appear to converge as they recede into the distance. This is because the converging lines suggest that the objects are farther away, even though they may actually be the same size as those closer to the viewer. Accommodation (the focusing of the lens in the eye) and stereopsis (the perception of depth based on the slight differences between the images received by each eye) are also important depth cues, but they are not directly relevant to the Ponzo illusion. Motion parallax (the change in the perceived distance of objects as the observer moves) is not applicable to the static image of the Ponzo illusion.
