Task: Answer the multiple-choice question.
Query: Which compound exhibits a 19.797% 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] O=C(Nc1ccc([N+](=O)[O-])cn1)c1ccc(Br)o1
[b] Cc1ccc(Cl)cc1NC(=O)CCC(=O)Nc1cc(Cl)ccc1C
[c] CCCC1=C(C(=O)OCC)C2(C(=O)Nc3ccc(C)cc32)C(C#N)=C(N)O1
Answer: b. Cc1ccc(Cl)cc1NC(=O)CCC(=O)Nc1cc(Cl)ccc1C
