C Correct answer
Explanation

Persistence of vision is the correct answer because the human eye retains an image for approximately 1/16th of a second after it disappears. This allows sequential still images shown rapidly (like in film at 24 frames per second) to blend into smooth continuous motion. Parallax view refers to apparent position changes, photoreception is the general process of detecting light, and vanishing point is an artistic perspective technique.
