I can at least tell you it isn't
The territory was divided into independent city-states. ( I got a zero.)
Nor the flat land, as I remember the Aztec farmed from "Floating gardens."
The Aztec traded everything. So, If it's supposed to fit all three of them, it's already out for that option. (And all of them traded.)
I think, It'd have to be the last option left then, Corn being an important crop. <u><em>It should be.</em></u>
