Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.466\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC(C)[C@H](NC(=O)N1CC(=O)Nc2ccccc21)C(=O)N[C@@H](Cc1c[nH]c2ccccc12)C(=O)O
b CCOC(=O)c1[nH]ncc1CN1CCCC(C(=O)c2cccc3ccccc23)C1
c O=C(CN1c2ccccc2Sc2ccccc21)N/N=C/c1ccc([N+](=O)[O-])cc1
d Cc1ccc(NC(=O)c2ccco2)c(NC(=O)COc2ccccc2)c1
Answer: c. O=C(CN1c2ccccc2Sc2ccccc21)N/N=C/c1ccc([N+](=O)[O-])cc1
