Best ResponseYou've already chosen the best response.1To show `whole numbers` are closed under `multiplication` We take `two whole numbers` and `multiply them` to get another whole number. This illustrates closure. So we need to `start with` two whole numbers. 1 is NOT a whole number. a, b, and c are not necessarily whole numbers, we don't know enough about them.

Best ResponseYou've already chosen the best response.1So we can't pick an option that is showing 1 in the multiplication and we can't pick the option with a,b and c's and stuff like that.
