Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.168\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1cccc(CN(C(=O)c2ccco2)C2CCS(=O)(=O)C2)c1
(b) O=C(NNS(=O)(=O)c1ccccc1)C1CC(c2cccnc2)=NO1
(c) O=C(c1cccnc1)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1
(d) CC(=O)c1ccc(NC2=NCCCS2)cc1
(e) COc1ccc(C(=S)N2CCCCC2)cc1Br
Answer: b. O=C(NNS(=O)(=O)c1ccccc1)C1CC(c2cccnc2)=NO1
