Correct answer: A — Popliteal sciatic plus saphenous nerve block
Foot innervation: sciatic (tibial + common peroneal = majority) plus femoral via saphenous nerve (medial ankle/foot). Popliteal sciatic alone misses saphenous territory. Combined popliteal sciatic + saphenous = comprehensive foot analgesia.
