b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
