Task: Answer the multiple-choice question.
Query: Which compound has a -1.420\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cc(OC)c(NC(=O)N2CCOCC2)cc1Cl
b O=C(CSc1ccc(-c2ccco2)nn1)Nc1cccc(F)c1
c Cc1ccc([N+](=O)[O-])cc1S(=O)(=O)Nc1ccc(OCC(=O)N2CCOCC2)cc1
d COc1ccc(C2Nc3ccccc3NC3=C2C(=O)CC(C)(C)C3)cc1O
Answer: b. O=C(CSc1ccc(-c2ccco2)nn1)Nc1cccc(F)c1
