The fibula is the smaller bone and bears relatively little weight. Which option best states this truth?

• A. It bears most of the body's weight
• B. It is the larger bone in the lower leg
• C. The fibula is the smaller bone and bears relatively little weight
• D. It forms the knee joint

Answer: (C)

The main idea is that weight in the lower leg is carried mostly by the tibia, while the fibula is the thinner, outer bone whose primary roles are muscle attachment and providing lateral stability at the ankle, not bearing most of the body's weight. The statement that the fibula is the smaller bone and bears relatively little weight correctly reflects its function. The other descriptions misstate its role: it is not the larger bone, it does not form the knee joint (that joint is mainly the femur with the tibia and patella), and while it articulates with the tibia and contributes to ankle stability via the lateral malleolus, its main responsibility is not weight support.
