The correct option is Facial (VII). The parasympathetic fibers of the facial (VII) nerve stimulate many large glands in the head such as the nasal and lacrimal glands.

Explanation:

Parasympathetic system fibers originate in the brain, as part of the cranial nerves and in the sacral (posterior) region of the spinal cord. Through quite long nerves, they extend to the organs on which they act, and each fiber synapses with a ganglion in the organ itself.  

The facial nerve (VII), is the seventh cranial nerve supplies motor fibers for facial expression muscles, in addition to a set of nerve fibers that emerge separately from the brainstem, called the intermediary nerve (VII bis or Wrisberg nerve ), which carry gustatory fibers and secretory-viscous effector fibers (parasympathetic). It has two roots, one motor and the other sensitive / parasympathetic (intermediate nerve). Its secretory effector visceral fibers (preganglionic), go to the submandibular and sphenopalatine ganglia (pterygopalatine) and innervate the submandibular, sublingual, lacrimal and mucous membrane glands of the nasal cavity and palate.
