Verified step by step guidance

Step 1: Understand the structural and anatomical differences between the listed bones (Femur, Clavicle, Mandible, Scapula). Each bone has unique properties that influence its susceptibility to fractures.

Step 2: Consider the location and function of the clavicle. The clavicle is a slender, S-shaped bone that connects the sternum to the scapula. Its position and shape make it prone to fractures, especially during falls or direct impacts.

Step 3: Compare the clavicle to the femur. The femur is the strongest and largest bone in the body, designed to bear weight and resist significant forces, making it less susceptible to fractures under normal circumstances.

Step 4: Evaluate the mandible. The mandible is the lower jawbone and is relatively strong due to its role in chewing and supporting the teeth. While it can fracture, it is less commonly injured compared to the clavicle.

Step 5: Assess the scapula. The scapula is a flat, triangular bone located in the upper back. It is protected by surrounding muscles and is less likely to fracture compared to the clavicle, which is more exposed and vulnerable.
