How far north do you live? Anyway, block as much as you can without having the radiator fan kick on much.
I voted for "C" because there was no "B+D" option, but I think you (and I) should permanently close the upper grille, and make an adjustable lower grille opening. That can be as simple as panels you remove when it gets warm out, or as complicated as cable-operated door you can use from the driver's seat.
Btw, nice car, and nice photoshop.
