At an antinode of a standing wave, the motion of a string element is characterized by maximum amplitude oscillations that are purely time-dependent, with no spatial (x) dependence in the equation. Choice E correctly represents this with a cosine function dependent only on time, indicating maximum oscillation at that point.
