Correct answer: A — Femur (popliteal surface)
The popliteal artery is the deepest structure in the popliteal fossa lying on the posterior surface of the distal femur and the posterior capsule of the knee joint. From superficial to deep: tibial nerve → popliteal vein → popliteal artery. The artery is vulnerable to injury in posterior knee dislocation and supracondylar femur fractures.
