Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.520% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CC(=O)CC1(O)C(=O)N(Cc2ccccc2)c2ccccc21
b: O=C(Nc1ccc(N2CCCCC2)c(Cl)c1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
c: O=C(N[C@H](CO)[C@H](O)c1ccc([N+](=O)[O-])cc1)C(Cl)Cl
Answer: c. O=C(N[C@H](CO)[C@H](O)c1ccc([N+](=O)[O-])cc1)C(Cl)Cl
