Muscles that move the eyeball have ________ fibers.
ozzi

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.

<h3>What are fast muscle fibers?</h3>

Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.

Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.

Therefore, the correct option is A.
