• A. Foot
• B. Knee
• C. Ankle
• D. Subtalar

Answer: (C)

This is about the ankle joint, specifically the talocrural joint. The medial malleolus (from the tibia) and the lateral malleolus (from the fibula) create a mortise that the talus fits into. This arrangement connects the lower leg to the foot and mainly allows up-and-down movement—dorsiflexion and plantarflexion. The subtalar joint, by contrast, sits between the talus and calcaneus and doesn’t involve the malleoli, while the knee is a separate joint between the femur, tibia, and patella.
