Task: Answer the multiple choice question.
Question: Which drug has a 7.871\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=S(=O)(NCc1ccccc1)NCc1ccccc1F
[b] O=C(O)Cc1sc(Nc2cccc3ccccc23)nc1-c1ccc(F)cc1
Answer: a. O=S(=O)(NCc1ccccc1)NCc1ccccc1F
