Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.873\% 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] S=C(Nc1ccc(Nc2ccccc2)cc1)NC1CCCCCC1
[b] O=c1cc(O)n(-c2ccc(F)cc2)c(=S)[nH]1
[c] C[N+](C)(C)c1ccccc1.[I-]
Answer: b. O=c1cc(O)n(-c2ccc(F)cc2)c(=S)[nH]1
