B) Middle cranial fossa
C) Posterior cranial fossa
D) None of the above

Answer 1

The facial nerve enters the internal acoustic meatus, which is located in the posterior cranial fossa.

Step-by-step explanation:

The facial nerve enters the internal acoustic meatus in the posterior cranial fossa. The internal acoustic meatus is located on the medial wall of the petrous ridge within the posterior cranial fossa, providing a passageway for both the facial nerve that supplies the muscles of the face and the nerve from the hearing and equilibrium organs of the inner ear.
