Task: Answer the multiple-choice question.
Question: Which compound exhibits a 15.222\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CC(Oc1ccccc1)C(=O)Nc1cccc([N+](=O)[O-])c1
b: O=C(C1CCCO1)N1CCN(S(=O)(=O)c2cccc3nsnc23)CC1
c: O=C(COC(=O)c1ccc([N+](=O)[O-])o1)NC1CCS(=O)(=O)C1
Answer: c. O=C(COC(=O)c1ccc([N+](=O)[O-])o1)NC1CCS(=O)(=O)C1
