The facial nerve (cranial nerve VII) primarily develops from the:

Answer:

C. 2nd pharyngeal arch

Explanation:

The facial nerve is associated with the second pharyngeal arch, also known as the hyoid arch. During embryonic development, different cranial nerves correspond to the various pharyngeal arches, and in this case, the facial nerve innervates the muscles derived from the second arch as well as providing sensory innervation to certain areas of the face. This development is crucial for the formation of structures such as the facial muscles and parts of the ear.
