Verified step by step guidance

Step 1: Understand the anatomy of the sternum, which is a flat bone located in the center of the chest and consists of three main parts: the manubrium (top), the body (middle), and the xiphoid process (bottom).

Step 2: Recognize that the xiphoid process is the smallest and most inferior part of the sternum. It is a bony projection that serves as an attachment point for muscles such as the diaphragm and the rectus abdominis.

Step 3: Eliminate the incorrect options: The manubrium is the upper part of the sternum, the clavicle is a separate bone that connects to the sternum at the sternoclavicular joint, and costal cartilage connects the ribs to the sternum but is not a bony projection.

Step 4: Confirm that the xiphoid process is the correct answer based on its anatomical location and function as the bony projection at the bottom of the sternum.

Step 5: Review the importance of the xiphoid process in clinical settings, such as its role in CPR and its vulnerability to injury during chest compressions.
