Task: Answer the multiple choice question.
Question: Which compound has a 0.975\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Nc1cc(Br)c(O)c(Br)c1)c1cccc(NC(=O)c2ccco2)c1
(b) CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)CSc1ccccc1C(=O)O
(c) CC(CN1CCOCC1)OC(=O)c1ccc(C(C)(C)C)cc1.Cl
Answer: a. O=C(Nc1cc(Br)c(O)c(Br)c1)c1cccc(NC(=O)c2ccco2)c1
