Answer: (B)

Verified step by step guidance

1. Step 1: Begin by identifying the anatomical regions associated with the shoulder and upper limb. The shoulder and upper limb include bones that are part of the pectoral girdle and the arm, forearm, and hand.
2. Step 2: Review the listed bones: Clavicle, Scapula, Humerus, and Femur. Determine which of these bones are part of the pectoral girdle or upper limb.
3. Step 3: Recall that the clavicle and scapula form the pectoral girdle, which connects the upper limb to the axial skeleton. The humerus is the bone of the upper arm, directly involved in the shoulder joint.
4. Step 4: Understand that the femur is the bone of the thigh and is part of the lower limb, not the shoulder or upper limb. This makes it anatomically distinct from the other listed bones.
5. Step 5: Conclude that the femur is the correct answer as it is NOT part of the shoulder and upper limb, while the clavicle, scapula, and humerus are all integral components of these regions.
