Which is the most cranial sternebra?

Explanation:
The idea being tested is the arrangement of the sternum from head to tail. The most cranial part of the sternum is the manubrium, the upper plate that forms the front of the thorax and connects with the first ribs (and often with the clavicles). The body of the sternum sits behind and below it as the central blade, and the xiphoid process is the small caudal tip. The coracoid process, meanwhile, is part of the shoulder girdle (the scapula) and not a sternum component. So the cranialmost sternebra is the manubrium.
