• B. Facial nerve
• C. Vagus nerve
• D. None of the above

Answer 1

Answer: (C)

Vagus nerve

The vagus nerve has the highest number of branches. It is the longest cranial nerve. It contains motor and sensory fibres and, because it passes through the neck and thorax to the abdomen, has the widest distribution in the body. It contains somatic and visceral afferent fibres, as well as general and special visceral efferent fibres. It is also called X cranial nerve or 10${}^{th}$ cranial nerve. So, the correct answer is option C.
