Task: Answer the multiple-choice question.
Question: Which compound exhibits a 7.693\% 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) COc1ccc(/C=C2\SC(=O)N=C2N)cc1
b) O=C(c1ccc([N+](=O)[O-])cc1)N1CCc2ccccc21
c) CCOC(=O)C1CCCN(C(=S)Nc2cccc(Cl)c2C)C1
Answer: b. O=C(c1ccc([N+](=O)[O-])cc1)N1CCc2ccccc21
