Which nerve innervates the tensor palatini?

Explanation:
The main idea here is understanding which nerve supplies the tensor veli palatini. This muscle tenses the soft palate and helps open the auditory (pharyngotympanic) tube during swallowing and yawning. Its motor innervation comes from the mandibular division of the trigeminal nerve (V3) via the nerve to the tensor veli palatini. This is distinct from the other palatal muscles, which receive their motor input from the pharyngeal plexus carried by the vagus nerve. So, among the options, the trigeminal nerve (specifically V3) is the correct innervation.
