Which arch forms the inferior portion of the hyoid bone?

Explanation:
During development, the hyoid bone forms from cartilage from the pharyngeal arches. The part from the second arch gives the lesser horn and the upper portion of the body, while the rest—the greater horn and the lower portion of the body—comes from the third arch. Since the inferior portion of the hyoid bone is the lower part near the greater horn, it is derived from the third arch.
