Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.195\% 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 additional words.
Options:
a: O=[N+]([O-])c1ccc(Nc2ccccc2)c2nonc12
b: O=C(COc1ccccc1)Nc1ccc([N+](=O)[O-])cc1
c: O=C1CC(c2ccccc2)C(=O)N1c1cccc(O)c1
Answer: b. O=C(COc1ccccc1)Nc1ccc([N+](=O)[O-])cc1
