Task: Answer the multiple choice question.
Question: Which compound exhibits a 14.346\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=[N+]([O-])c1ccc(CSc2ccc(-c3ccccn3)nn2)cc1
[b] COc1cccc(NC(=O)c2ccc(-c3ccccc3[N+](=O)[O-])o2)c1
[c] O=[N+]([O-])C(=C1Nc2ccccc2N1)/C(Cl)=C(/Cl)Br
Answer: c. O=[N+]([O-])C(=C1Nc2ccccc2N1)/C(Cl)=C(/Cl)Br
