Final answer:
The optic nerve is the second cranial nerve, not the first; the first is the olfactory nerve. The facial nerve (CN VII) contains preganglionic parasympathetic fibers.
Step-by-step explanation:
The statement that the first pair of cranial nerve is the optic nerve is false.
The first cranial nerve is actually the olfactory nerve (CNI), which is responsible for the sense of smell. The optic nerve is indeed a cranial nerve, but it is the second one, known as CNII. Regarding the question about which cranial nerve contains preganglionic parasympathetic fibers, the correct answer is b. facial, CN VII. The facial nerve has fibers that control various functions including the salivary glands, and this nerve is responsible for conveying gustatory, or taste, sensations.
