Solution
The correct option is C The Hyoid Bone The hyoid is a bone found in animals’ necks and it aids in things like tongue and other muscle movements. If the ossification of this bone is not complete, it allows for an elongated vocal tract, thus making it possible for lions, tigers, leopards, and jaguars to roar. An incompletely ossified hyoid may mean roaring, but it also means interrupting what is usually a constant purr.
