Explanation:

Caloric study is a vestibular test. The vestibulocochlear nerve (CN VIII) is responsible for the vestibular (balance) and auditory (hearing) functions. This test evaluates the vestibular part of CN VIII by introducing warm or cold water/air into the ear and observing eye movements (nystagmus). CN V (trigeminal) is for facial sensation and mastication. CN XI (accessory) controls neck and shoulder muscles. CN X (vagus) is involved in many visceral functions.

Answer:

CN VIII
