Correct answer: C — Mylohyoid

The mylohyoid muscle is innervated by the mylohyoid nerve (a branch of the inferior alveolar nerve from V3) but is classified as a suprahyoid muscle, not a muscle of mastication. The four muscles of mastication (masseter, temporalis, medial pterygoid, lateral pterygoid) are all innervated by V3. Other V3-innervated muscles that are not muscles of mastication include the anterior belly of digastric, tensor veli palatini, and tensor tympani.
