Task: Answer the multiple-choice question.
Query: Which compound exhibits a 10.489\% 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(CN1c2cccc3cccc(c23)S1(=O)=O)NCc1ccc(Cl)cc1
[b] COC(=O)/C(C(C)=O)=C(\C=C\N(C)C)N(C)C
[c] CC(=O)Nc1ccc(NC(=O)COC(=O)c2n[nH]c3ccccc23)cc1
Answer: b. COC(=O)/C(C(C)=O)=C(\C=C\N(C)C)N(C)C
