This muscle functions to allow you to stand on your heels
A
gastrocnemius
B
tibialis anterior
C
peroneus
D
sartoris
Explanation: 

Detailed explanation-1: -The plantaris tendon runs below both the soleus and gastrocnemius muscles to connect directly with the heel bone. This muscle works with the Achilles tendon to flex both the ankle and knee joints, allowing a person to stand on their toes or point their foot in plantar flexion.

Detailed explanation-2: -Function. Tibialis anterior is the primary dorsiflexor of the ankle with synergistic action of extensor hallicus longus, extensor digitorium longus and peroneous tertius. Inversion of the foot. Adduction of the foot.

Detailed explanation-3: -Function. Tibialis anterior dorsiflexes the foot at the talocrural joint and inverts it at the subtalar joint. It plays an important role in the activities of walking, hiking and kicking the ball by stabilizing the ankle joint as the foot hits the floor and pull it clear of the ground as the leg continues moving.

Detailed explanation-4: -The tibialis posterior acts to plantarflex the foot and invert the foot and support the medial arch. The muscles of the anterior compartment primarily antagonize the posterior compartment muscles. Collectively, the anterior muscles dorsiflex the foot at the ankle joint.
