Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.187\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) Cc1cc(C(=O)Nc2ccc(C)c(C)c2)n(-c2ccccc2)n1
b) O=S(=O)(c1ccc(F)c(Cl)c1)N1CCCC1
c) COC(=O)c1ccc(Nc2c([N+](=O)[O-])c(=O)oc3ccccc23)cc1
d) CC(=O)c1ccc(NC(=O)CCc2c(C)nn(-c3ccc(N4CCOCC4)nn3)c2C)cc1
e) CC1CC(C)CN(S(=O)(=O)c2ccc(C(=O)NCCCn3ccnc3)cc2)C1
Answer: b. O=S(=O)(c1ccc(F)c(Cl)c1)N1CCCC1
