Task: Answer the multiple-choice question.
Query: Which compound exhibits a 18.564% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(NNc1cc(N2CCOCC2)nc(N2CCOCC2)n1)c1ccc(Cl)c(Cl)c1
(b) Cc1ccc(Cl)cc1N1CCN(CC(O)COCc2ccco2)CC1.O=C(O)C(=O)O
(c) O=[N+]([O-])c1ccc(/C=C/c2ccc3cccc(O)c3n2)cc1
(d) Cc1cc(OCC(=O)Nc2ccc(N3CCN(C)CC3)cc2)ccc1Cl
Answer: c. O=[N+]([O-])c1ccc(/C=C/c2ccc3cccc(O)c3n2)cc1
