Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.690\% 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] CCOC(=O)C1=C(c2ccccc2)NC(N)=NC1c1ccc(OCc2ccc(C(=O)OC)cc2)cc1
[b] COc1ccc([N+](=O)[O-])cc1N(CC(O)CN(CC(C)C)CC(C)C)S(=O)(=O)c1ccc(C)cc1.Cl
[c] Cn1c(SCC(=O)Nc2cc(C(C)(C)C)nn2-c2ccccc2)nc2ccccc21
[d] CCCCN1C(=O)Nc2ccccc2S1(=O)=O
[e] CC(=O)/C(=N/Nc1ccc(C)cc1)Sc1nnc(CCc2ccccc2)n1-c1ccccc1
Answer: b. COc1ccc([N+](=O)[O-])cc1N(CC(O)CN(CC(C)C)CC(C)C)S(=O)(=O)c1ccc(C)cc1.Cl
