Option A is correct. This patient has signs of involvement on cranial nerves V (decreased facial sensation), VII (facial weakness) and VIII (vertigo, hearing loss, balance problems). The most common cause of this clinical picture is an acoustic neuroma, which is actually a schwannoma that forms at the cerebellopontine angle.
