The knee joint is innervated by the femoral nerve (L2-L4), the tibial nerve (L4-S3), and the common fibular nerve (L4-S2). However, the majority of the innervation comes from the femoral and tibial nerves, which arise from the L3-S2 segments of the spinal cord. Therefore, choice C (L3-S2) is the best option.
