Task: Answer the multiple choice question.
Query: Which compound has a 7.969\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CC1CCN(C(=O)COC(=O)COc2ccccc2C#N)CC1
[b] COc1ccc(OCCC(=O)Nc2nccs2)cc1
[c] O=C(Nc1ccccc1-c1ccccc1)c1ccc(Cl)c([N+](=O)[O-])c1
[d] COc1ccccc1NC(=O)c1ccc(NC(=O)CSc2ncn[nH]2)cc1
Answer: c. O=C(Nc1ccccc1-c1ccccc1)c1ccc(Cl)c([N+](=O)[O-])c1
