I vote Option 1.
I'm an armchair aero geek, and know nothing of aerodynamics, but I would think that Option 1 might be a fraction of a percent better.
I base this guess on the fact that every trip strip / air ramp that I have seen, is located at least two inches within the area of the car that has a radiused edge.
Some good examples are the pictures you posted. If you notice, the body panel begins to curve a couple of inches before the trip strip.
However, there are some exceptions, such as the air ramp on the Ford Focus tailights :
A curious thing abou the Focus is the fact that the air ramp is there on a section of the light, but directly below it is a massive round edge to the bumper and area above the air ramp.
