Answer:      

A. The d. extensor retinacula are the broad ligamentous sheets that contain the tendons of the anterior compartment muscles.

B. Inversion and dorsiflexion of the foot is achieved by contracting the a. tibialis anterior muscle.

C. The b. extensor hallucis longus muscle has a skeletal attachment on the distal phalanx of the first digit.

D. The c. lateral condyle of the tibia is a skeletal attachment site of the tibialis anterior muscle.

Explanation:

The two extra options are the f. extensor digitorum longus and the e. medial epicondyle. The first one is a muscle in the anterior part of the legs that originates in the anterior lateral condyle of the tibia and the anterior part of the fibula. Its insertion is in the four phalanges of the 2, 3, 4, and 5 digits. The first digit has the insertion of the extensor hallucis longus. The extensor digitorum longus and the b. extensor hallucis longus has the same function, the extension of the toes, the extensor hallucis longus only extends the first digit, and the extensor digitorum longus extends the other four digits simultaneously.

The second extra option, the medial epicondyle, is in the femur. It is a prominence in the distal part of this bone. The tibial collateral ligament and the Magnus muscle insert in this part of the femur.
