Final answer:
The proximal fibula articulates with the tibia at the proximal tibiofibular joint, and the distal fibula forms the lateral malleolus and is part of the ankle joint. The coxal bone is known as the hip bone. Therefore correct option is B
Step-by-step explanation:
The proximal fibula articulates with the underside of the lateral condyle of the tibia, forming the proximal tibiofibular joint. The distal fibula forms the lateral malleolus, a bony prominence on the lateral aspect of the ankle, and it articulates with both the fibular notch of the tibia and the talus bone as part of the ankle joint. As for the coxal bone referred to in the question, it is commonly known as the hip bone.
