(A) The $12$ pairs of cranial nerves are classified based on their function as sensory,motor,or mixed.$1$. Sensory nerves: These carry sensory information to the brain. The purely sensory cranial nerves are the Olfactory $(I)$,Optic $(II)$,and Vestibulocochlear $(VIII)$ nerves.$2$. Motor nerves: These control muscle movement. Examples include Oculomotor $(III)$,Trochlear $(IV)$,Abducens $(VI)$,Accessory $(XI)$,and Hypoglossal $(XII)$ nerves.$3$. Mixed nerves: These contain both sensory and motor fibers. Examples include Trigeminal $(V)$,Facial $(VII)$,Glossopharyngeal $(IX)$,and Vagus $(X)$ nerves.Therefore,the correct option is $A$.
