Task: Answer the multiple choice question.
Query: Which compound has a 12.721\% 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] CCCCN(C(=O)c1cccc(-n2cnnn2)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
[b] COc1ccc(N=C2C(=Nc3ccc(OC)cc3)N(c3ccc(OC)cc3)C(=S)N2c2ccccc2)cc1
[c] COC(=O)/C=C1/S/C(=N/NC(=O)c2ccc(Cl)cc2Cl)NC1=O
Answer: b. COc1ccc(N=C2C(=Nc3ccc(OC)cc3)N(c3ccc(OC)cc3)C(=S)N2c2ccccc2)cc1
