Final answer:

The oculomotor nerve supplies the superior rectus, inferior rectus, medial rectus, and inferior oblique intraocular muscles, responsible for various eye movements. The correct answer to the question is option (c).

Step-by-step explanation:

The oculomotor nerve supplies four intraocular muscles: the superior rectus, the inferior rectus, the medial rectus, and the inferior oblique. Contractions of these muscles coordinate to move the eye in various directions. The superior rectus muscle is involved in looking upwards, the inferior rectus in looking downwards, the medial rectus in adduction (moving the eye toward the nose), and the inferior oblique contributes to extorsion and looking up.

Option (c) Superior rectus, Inferior rectus, Medial rectus, Inferior oblique is the correct answer. The lateral rectus muscle is innervated by the abducens nerve, and the superior oblique is innervated by the trochlear nerve.
