Are cranial nerves I, III, VI, VIII, VIIII, and X all considered motor nerves?

Cranial nerves include a combination of sensory, motor, and mixed functions, which means they can carry either sensory information, motor commands, or both. Cranial nerve I (olfactory) is purely sensory, responsible for the sense of smell. Cranial nerves III (oculomotor), IV (trochlear), and VI (abducens) are primarily motor, innervating muscles that control eye movement. However, cranial nerve VIII (vestibulocochlear) is predominantly sensory, involved in hearing and balance. Cranial nerve IX (glossopharyngeal) and X (vagus) are mixed nerves, having both motor and sensory components, participating in functions such as taste sensation and autonomic control of the heart.

In this instance, the statement that all these cranial nerves are considered motor is inaccurate, as several of them are not exclusively motor, affirming that the correct response is false.
