OPTION 4

The ansa cervicalis supplies all the infrahyoid muscles except the thyrohyoid muscle. The thyrohyoid muscle is innervated by the first cervical nerve, which accompanies the hypoglossal nerve for a short distance. 
The ansa cervicalis is a component of the cervical plexus. It gives muscular branches to the geniohyoid muscle of the suprahyoid group and most of the infrahyoid (strap) muscles. The ansa cervicalis supplies the three out of four infrahyoid muscles: omohyoid, sternothyroid, and sternohyoid.
