Option A or B?

hi! I'm applying to Amherst rd and was wondering if anyone knows if its better to submit option A or B for the writing sup. I feel like A is the more common route, and would be more standardised (I presume more people submit for A?). I feel pretty confident in my abilities to write a decent sup for option A, however I also have a few graded papers that I feel are pretty strong and could work well for B. I'm currently taking the IB and am predicted an A (32/34) for my extended essay in HL global politics. Considering I want to study poli sci, would it be best to submit this paper and just go with B? thanks :)
