<reasoning>

Identify the anatomical connections

Using the Skeletal Anatomy and Bone Identification knowledge points:

• The question asks for the bone that joins the sternum (breastbone) and the scapula (shoulder blade).
• The clavicle (collarbone) is an S-shaped long bone that articulates medially with the sternum (sternoclavicular joint) and laterally with the acromion process of the scapula (acromioclavicular joint).

Evaluate the given options

Using the Skeletal System knowledge point:

• scapula: This is the shoulder blade itself; a bone cannot join itself to the sternum.
• humerus: This is the upper arm bone, which articulates with the scapula but does not connect directly to the sternum.
• tibia: This is the shinbone located in the lower leg.
• ulna: This is one of the two forearm bones.
• clavicle: This bone acts as a strut connecting the upper limb to the axial skeleton by joining the sternum and scapula.
