Answer:
D. Femoreal vein.
Explanation:
Close to the popliteal artery, the popliteal vein extends and transports blood from the knee (and also the muscles from the thigh and calf) once again up to the heart. This vein has its origin in the joint between both the anterior and posterior tibial veins, proximal to the knee. 
Also, the popliteal vein starts its extension from the popliteal artery, which can be found behind the knee, and the drainage of the peroneal vein is performed by it prior to reaching the knee joint, where the popliteal vein becomes known as the femoral vein.
