Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.907\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cn1c(O)c(N=NC(=O)CNC(=O)c2ccccc2)c2cc(Br)ccc21
[b] O=C(NCc1ccc(F)cc1)c1ccncc1
[c] O=C(Nc1nnc(-c2ccccc2SCc2ccccc2F)s1)Nc1ccccc1F
Answer: b. O=C(NCc1ccc(F)cc1)c1ccncc1
