Which of these 2 chemicals would make the best muscle relaxant and why?

hey, im not 100 percent sure on this one, but i think if you flood the cytoplasm with calcium ions the muscles will contract and u want them to relax. so i would go with A. i think every muscle relaxant works with acetylcholine. to double check, do a search on Flexeril on webmd or any medical site. hope this helps
