Which of the following lists all six extraocular muscles?

Explanation:
Extraocular muscles are the six muscles that move the eyeball itself. They consist of four rectus muscles (medial, lateral, superior, inferior) and two oblique muscles (superior, inferior). The list that includes exactly these six names matches the muscles that move the eye in all directions. Other options mix in eyelid muscles like orbicularis oculi and levator palpebrae superioris, or intraocular structures such as the ciliary muscle, iris sphincter, zonules, and retina, which are not extraocular muscles. So the correct list is the one that includes Medial Rectus, Inferior Rectus, Lateral Rectus, Superior Rectus, Superior Oblique, and Inferior Oblique.
