Correct answer: D — Median nerve

The medial plantar nerve (from tibial nerve) is the analogue of the median nerve in the hand: it supplies the medial 3.5 digits and the first two lumbricals. The lateral plantar nerve is the analogue of the ulnar nerve: it supplies the lateral 1.5 digits and the interossei. This pattern mirrors the hand innervation.
