Final answer:
The clavicle is the bone that reacted similarly to long bones according to Langley, serving as a support and protective structure for the upper limb.
Step-by-step explanation:
According to Langley, the clavicle is the bone that reacted similarly to long bones. The clavicle, also known as the collarbone, is considered a long bone despite its horizontal positioning in the body.
It has several important functions, such as serving as a strut to support the scapula, transmitting forces acting on the upper limb to the sternum and axial skeleton, and protecting underlying nerves and blood vessels that pass between the trunk and the upper limb. Therefore, the correct answer is B) Clavicle.
