Solution
The correct option is D Facial
- The facial nerve is the seventh cranial nerve, or simply CN VII.
- It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
- The facial nerve also supplies parasympathetic fibers to the submandibular gland and sublingual salivary glands via chorda tympani to increase salivary secretions.
- Hence Facial cranial nerve is involved in secretions.
- So, the correct answer is 'Facial'.
