Task: Answer the multiple-choice question.
Query: Which compound has a -19.217% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cc(/C=N/NC(=O)C(N)=O)cc(OC)c1O
b CCOC(=O)C1CN(S(=O)(=O)c2ccc(OC)cc2)c2cc(CC(=O)OC)ccc2O1
c O=C(CSc1nnc(NC(=O)c2ccc(S(=O)(=O)N3CCOCC3)cc2)s1)Nc1ccccc1C(F)(F)F
d Cc1cc(Cl)c(S(=O)(=O)Nc2ccc(Cl)cn2)cc1OCC(N)=O
Answer: b. CCOC(=O)C1CN(S(=O)(=O)c2ccc(OC)cc2)c2cc(CC(=O)OC)ccc2O1
