The correct answer is E. Saying "la" requires the tongue to be placed against the roof of the mouth, which can not be accomplished if the hypoglossal nerve (CN XII) is non-functional. CN XII innervates the intrinsic muscles of the tongue.
The facial nerve, CN VII (choice A), is needed to move the lips while saying "mi." CN VII innervates the muscles of facial expression.
The vestibulocochlear nerve, CN VIII (choice B), mediates hearing and maintains equilibrium and balance.
The vagus nerve, CN X (choice C), is needed to raise the palate while saying "kuh."
The spinal accessory nerve, CN XI (choice D), mediates head and shoulder movements.

palatoglossus is tongue m. so i dont think it is involved in aah.. but nerve responsible is vagus X
