(D) The presence of a $diaphragm$ is a unique characteristic of mammals. It is a muscular partition that separates the thoracic cavity from the abdominal cavity and plays a crucial role in the mechanism of breathing. While other vertebrates may have a four-chambered heart (like birds) or exhibit homeothermy (like birds), the $diaphragm$ is exclusively found in mammals.
