I'm just a dumb beginner, but I voted 'C' b/c you need to have both ends working together, complimenting each other. You can have either end 'off' a little and most people would never notice it. You need the shock to keep the tire on the ground and the power to the ground, but you also need the forks to keep the tire going where you want it to go. And then there's the load absorbstion (sp?). If you have no shock, you could end up with a taco'd wheel and/or broken frame. If you have no fork, you could end w/a taco'd wheel and/or something in the front broken(bars, head tube gusset, etc.). W/out the sus., front and rear equally, you'll have problems.
