Task: Answer the multiple-choice question.
Query: Which compound has a 19.578\% 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 additional words.
Options:
[a] O=Cc1cccc(OCc2cccc3ccccc23)c1
[b] O=C(CSc1nc(-c2ccccc2Cl)ns1)c1ccc(Cl)cc1
[c] COc1cc(NC(=O)COC(C)=O)c(C)cc1[N+](=O)[O-]
Answer: c. COc1cc(NC(=O)COC(C)=O)c(C)cc1[N+](=O)[O-]
