Which muscles evert the foot?

• A. Peroneus longus and extensor digitorum longus
• B. Tibialis anterior
• C. Tibialis posterior
• D. Flexor digitorum longus

Answer: (A)

Turning the sole outward is eversion, which mainly comes from the lateral group of calf muscles that run along the fibula. The primary muscles responsible are the fibularis (peroneus) longus and fibularis brevis. In this item, the pairing includes a true evertor (peroneus longus), and the other muscle listed—extensor digitorum longus—does not primarily evert the foot; its main roles are dorsiflexion of the ankle and extension of the toes, with any eversion contribution being minimal. The other options point to muscles that invert the foot or are primarily involved in dorsiflexion or toe flexion, not eversion, so they don’t fit as the muscles that evert.
