Option A (I'm leaning towards this one). I center the drawer pulls on the top 2 solid drawer fronts. These are 5" high drawer fronts. I then center the shallower depth frame/panel pull, and then take this offset from the top edge and apply it to the final, lowest handle.

handle/knob location test
I'm pretty sure you want to center knobs on the level defined by the inboard edge of the rail in your door panel like so
Still not sure how to locate the hoop pulls for drawers. Are they centered on rails for the frame/panels, or do you locate them at the center of the panel itself of the topmost frame/panel, and then use the same distance from top of panel to locate the handles on the lower, deeper drawers?
