Vedclass · Answer

(B) Whales,bats,and rats are all members of the class $Mammalia$. One of the defining characteristics of mammals is the presence of a muscular diaphragm that separates the thoracic cavity from the abdominal cavity. This structure plays a crucial role in respiration. While some mammals have external ears (pinnae),not all do (e.g.,whales have internal ear openings). Extra-abdominal testes are not a universal feature of all mammals (e.g.,in whales,testes are abdominal). Therefore,the presence of a muscular diaphragm is the most accurate common feature among these organisms.
