Through which foramen does CN VII exit?

  1. Foramen rotundum

  2. Foramen ovale

  3. Stylomastoid foramen

  4. Jugular foramen

The correct answer is: Stylomastoid foramen

CN VII, also known as the facial nerve, exits through the stylomastoid foramen. This is the only foramen on the list that is directly associated with the exit of the facial nerve. The other options are associated with different structures and cranial nerves. For example, the foramen rotundum is associated with the trigeminal nerve (CN V), the foramen ovale is associated with the mandibular branch of the trigeminal nerve (CN V3), and the jugular foramen is associated with multiple cranial nerves, including CN IX, CN X, and CN XI. Therefore, C is the only correct answer.
