**Core Concept**
The rectus muscles of the eye are responsible for converging and diverging eye movements, and their innervation is crucial for precise eye movement control. The oculomotor nerve (CN III) primarily supplies the medial rectus, superior rectus, inferior rectus, and inferior oblique muscles.

**Why the Correct Answer is Right**
The levator palpebrae superioris muscle, which is responsible for eyelid elevation, is not supplied by the oculomotor nerve. Instead, it is innervated by the sympathetic nervous system via the superior cervical ganglion and the oculomotor nerve's parasympathetic fibers. However, the levator palpebrae superioris is actually innervated by sympathetic fibers and the oculomotor nerve's parasympathetic fibers don't innervate it directly. It is actually the superior rectus muscle that is innervated by the oculomotor nerve but also has a branch from the sympathetic nervous system. However, the correct answer is not the superior rectus. The correct answer is the levator palpebrae superioris which is actually involved in eyelid elevation.

**Why Each Wrong Option is Incorrect**
**Option A:** The medial rectus muscle is supplied by the oculomotor nerve, making this option incorrect.
**Option B:** The superior rectus muscle is supplied by the oculomotor nerve, making this option incorrect.
**Option C:** The inferior rectus muscle is supplied by the oculomotor nerve, making this option incorrect.

**Clinical Pearl / High-Yield Fact**
Recall the mnemonic "SOOIS" for the rectus muscles innervated by the oculomotor nerve: Superior, Oblique, Ocular motor (medial rectus is often implied), Inferior, and Superior (again, referring to the superior rectus).

**Correct Answer: D. Levator palpebrae superioris.
