Answer
Scutellum
Reason — The single cotyledon of a maize grain is called Scutellum.
The hypocotyl is the part of the embryo axis between the cotyledons (or cotyledon and radicle). It is not a cotyledon itself. The coleorhiza is a protective sheath covering the radicle in monocot seeds like maize. The embryo is the whole young plant inside the seed, which includes cotyledon, radicle, plumule, etc., not just the cotyledon.
