Problem statement: Answer the multiple choice question.
Query: Which compound has a -5.345\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CC(=O)/C(C#N)=C1\NC(=O)C(Cc2ccc(C)c(Cl)c2)S1
(b) CC(C)C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2Cl)CC1
(c) CCN(CC)c1ccc(CN(C(=O)c2ccco2)C2CCS(=O)(=O)C2)cc1
Answer: b. CC(C)C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2Cl)CC1
