Task: Answer the multiple-choice question.
Question: Which compound exhibits a -19.459% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(Nc1cc([N+](=O)[O-])ccc1O)c1cccc(C(=O)Nc2cc([N+](=O)[O-])ccc2O)c1
[b] CC(=O)Oc1ccc(C(=O)c2ccccc2)c(OC(C)=O)c1
[c] CCOC(=O)CNC(=O)COc1ccc(Cl)cc1Br
[d] COC(=O)c1ccccc1NC(=O)CN1CCC(C(=O)c2ccc3c(c2)OCCO3)CC1
[e] CCOC(=O)C1=C(C)C/C(=N\NC(=O)c2ccccc2O)CC1
Answer: c. CCOC(=O)CNC(=O)COc1ccc(Cl)cc1Br
