D

E

Explanation: 

Detailed explanation-1: -Neuroanatomy, Cranial Nerve 10 (Vagus Nerve)

Detailed explanation-2: -The vagus nerve is the longest cranial nerve. It contains motor and sensory fibers 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 fibers, as well as general and special visceral efferent fibers. (See Table 1, below.)

Detailed explanation-3: -The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system. These functions are involuntary, meaning you can’t consciously control them.

Detailed explanation-4: -The vagus nerve is a mixed nerve, as it contains both afferent (sensory) and efferent (motor) fibers. This means it is responsible for not only carrying motor signals to the organs it innervates, but it also carries sensory information from these organs back to the central nervous system.
