I liked C with the spoiler option as well, opening a bit better shape to better blend with the upper opening like patrick suggested.
Don't love the turn signals myself on C, and would still like to see NACA ducts or similar integrated in to the opening for ducting front brakes.
I guess what I am telling you to build is basically what I will be trying to make for myself and my car heh.
