The correct option is
C Mixed
The cranial nerve VII or the facial nerve originates from the pons region of the hindbrain, which is also a part of the brainstem. It is a mixed nerve because the different branches of the nerve perform the functions of motor neurons and sensory neurons. It innervates the face, neck, taste buds and salivary gland. It receives the sensation of taste from the anterior 2/3 part of the tongue. It provides an impulse for the facial expression and the secretion of the saliva.
Hence, the correct answer is 'Mixed'
