Task: Answer the multiple choice question.
Question: Which compound has a 4.260\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CC(=O)N1C(=O)CC(C)N(C(C)=O)c2ccc([N+](=O)[O-])cc21
b. CCOC(=O)C1C(=O)C=C(/C=C/c2ccc(N(C)C)cc2)CC1c1ccccc1
c. C=CCOc1ccc(CN(C)C(=O)C2CCCO2)cc1
Answer: a. CC(=O)N1C(=O)CC(C)N(C(C)=O)c2ccc([N+](=O)[O-])cc21
