Task: Answer the multiple-choice question.
Query: Which drug exhibits a -9.143% 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 CCOCC(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
b CC1=N/C(=C\c2ccc([N+](=O)[O-])cc2)C(=O)N1c1cc(Cl)ccc1C
c O=C(CCCN1C(=O)/C(=C/c2ccco2)SC1=S)Nc1cccc(C(=O)O)c1
d O=C(Cn1ncc2c(=O)oc3ccccc3c21)N1CCc2ccccc2C1
Answer: b. CC1=N/C(=C\c2ccc([N+](=O)[O-])cc2)C(=O)N1c1cc(Cl)ccc1C
