The only direct connection between the pectoral girdle and the axial skeleton is where the clavicle articulates with the humerus. vertebral column articulates with the sacrum. clavicle articulates with the xiphoid process. coxal bones articulate with the femur. clavicle articulates with the manubrium of the sternum.

There are two bones that form the pectoral girdle and they are: scapula and clavicle.

The bones that form the axial skeleton consists of the bones of the head, trunk and vertebrate. For example sternum, ribcage, skull bones ...

In those options the only possible choice is: clavicle articulates with the xiphoid process. Clavicle from the pectoral girdle articulates with a part of the sternum (a axial bone).
