c. motion parallax

Explanation:

Motion parallax is the term that states that things closest to our eyes seem to move faster than things that are distant to our eyes. This explains the phenomenon that is happening to David, because when he travels by train he realizes that the trees and telephone poles near the tracks seem to flash (this is because these objects are close to his eyes) while buildings, trees and the more distant mountains seem to move slower (because they are far from his eyes).
