Task: Answer the multiple choice question.
Question: Which compound exhibits a 16.144\% 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] COc1ccc(C2(c3ccc(OC)cc3)NC(=O)N(CC(=O)N(C)c3ccccc3)C2=O)cc1
[b] c1ccc(C[C@H]2CNCCN2CCc2cccc3ccccc23)cc1
[c] Cc1cccc(OCC(=O)N2CCN(Cc3ccc([N+](=O)[O-])cc3)CC2)c1.O=C(O)C(=O)O
Answer: a. COc1ccc(C2(c3ccc(OC)cc3)NC(=O)N(CC(=O)N(C)c3ccccc3)C2=O)cc1
