Answer:
c. motion parallax
Step-by-step explanation:
It is a phenomenon derived from parallax, but instead involving locomotion thus, motion parallax. This is results in a 'depth cue' with moving objects. Because Dave is seeing objects at different lines of sight. There is a difference between the apparent movement of of the object and the actual displacement. Therefore objects closer move faster and further compared to objects farther away. Whereas the other options do not involve this type of explanation.
