Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.332\% 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) Cc1nc(Cl)nc(N(C)c2ccccc2)c1[N+](=O)[O-]
(b) CCOC(=O)[C@@H]1[C@H]2COc3ccccc3[C@@H]2N2C(=O)N(c3cccc(Cl)c3)C(=O)[C@]12C
(c) CCOC(=O)C1=C(C)N=c2s/c(=C\c3cccc(OCC(=O)O)c3)c(=O)n2C1c1ccccc1OC
Answer: b. CCOC(=O)[C@@H]1[C@H]2COc3ccccc3[C@@H]2N2C(=O)N(c3cccc(Cl)c3)C(=O)[C@]12C
