D
scapula
Explanation: 

Detailed explanation-1: -The xiphoid process can be broad, thin, monofid, bifid, trifid, curved, deflected, and contain foramina [1-3]. Current textbooks and human anatomy atlases depict the xiphoid process as a single, straight, fully ossified bone on the inferior aspect of the sternum corpus.

Detailed explanation-2: -The xiphoid process is a small, triangular part of the sternum that starts out as cartilage and eventually hardens as a person ages. Its main function is to act as a muscular attachment for other muscles in the area. Xiphoid process pain may produce discomfort and swelling. However, it is rarely a cause for concern.
