Verified step by step guidance

Begin by understanding the function of cranial nerves. Cranial nerves can be sensory, motor, or both. Sensory nerves are responsible for transmitting sensory information from the body to the brain.

Review the list of cranial nerves provided in the problem: Vagus nerve (CN X), Hypoglossal nerve (CN XII), Olfactory nerve (CN I), and Facial nerve (CN VII).

Identify the function of each cranial nerve: The Vagus nerve (CN X) is both sensory and motor, involved in autonomic functions. The Hypoglossal nerve (CN XII) is primarily motor, controlling tongue movements. The Olfactory nerve (CN I) is purely sensory, responsible for the sense of smell. The Facial nerve (CN VII) is both sensory and motor, involved in facial expressions and taste.

Focus on the Olfactory nerve (CN I), which is the only nerve in the list that is purely sensory. It carries sensory information related to smell from the nasal cavity to the brain.

Conclude that the Olfactory nerve (CN I) is the correct answer as it is the only cranial nerve listed that is purely sensory.
