Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. it is most likely:
a gymnosperm
a monocot
a eudicot
a basal angiosperm

a monocot

Explanation:

Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.

Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.
