Which of the following is not a component of or related to the rib cage?

The rib cage is a bony structure in the thorax that protects vital organs like the heart, lungs, and other major vessels while also serving as a framework for breathing. It is composed of the thoracic vertebrae, ribs, and sternum.

The sternum is a part of the chest that connects to the rib bones to form the front of the rib cage. It is located in the centre of the thorax.

The Clavicle is a long bone that connects the arm to the sternum in the shoulder.

The Scapula, also known as the shoulder blade, is a flat bone in the back of the shoulder that serves as an attachment point for several muscles that move the arm.

The femur is the longest, largest, and most powerful bone in the human body. It runs from the hip to the knee and connects the pelvic bone to the tibia to form the knee joint.
