Task: Answer the multiple choice question.
Question: Which compound has a 9.215\% 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: O=C(/C(=C(\[O-])c1ccccc1)[n+]1ccc2ccccc2c1)c1ccc(Cl)cc1
b: CCOC(=O)C1=C(C)NC(C)=C(C(=O)OCC)C1C(=O)OCC(=O)NC(C)C
c: COc1cccc(OC)c1C(=O)Nc1cc(C)nn1-c1nc2ccccc2[nH]1
Answer: a. O=C(/C(=C(\[O-])c1ccccc1)[n+]1ccc2ccccc2c1)c1ccc(Cl)cc1
