Final answer:
The lateral articulation within the ankle joint is between the talus and the lateral malleolus of the fibula, which is part of the ankle's stabilizing structure (Option C).
Step-by-step explanation:
The ankle joint, also known as the talocrural joint, involves articulations between the talus bone of the foot and the ends of the tibia and fibula. Specifically, the lateral articulation within the ankle joint is formed between the talus and the lateral malleolus of the fibula. This joint is a uniaxial hing* joint that permits dorsiflexion and plantar flexion of the foot.
The lateral malleolus, being the distal end of the fibula, forms a bony prominence that can be palpated on the lateral side of the ankle and firmly holds the talus in place laterally. Strong ligaments such as the anterior talofibular ligament and the posterior talofibular ligament also extend from the lateral malleolus of the fibula to the talus, providing stability to the ankle joint.
Thus, the correct option is C.
