Solution
The correct option is D Palatoglossus The twelveth nerve of the brain is known as the hypoglossal cranial nerve. The nerve is completely motor in action. This nerve innervates all the muscles in the tongue except the palatoglossus muscle. These are the membranous structures present surrounding the tonsil and which arise from the soft palate.
