Which cranial nerves contribute to the parasympathetic nervous system?

Explanation

The parasympathetic fibers of the cranial nerves are carried by cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus). These nerves are primarily responsible for parasympathetic innervation to various organs. The other options include nerves that do not participate in parasympathetic pathways.
