Task: Answer the multiple choice question.
Question: Which compound has a 4.308\% 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) CCSc1nc(C(F)(F)F)cc(=O)n1-c1ccccc1
(b) CCCCC(=O)Nc1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)cc1OC
(c) CCOc1nc2cnccc2n(CC(=O)Nc2cccc(C)c2C)c1=O
Answer: c. CCOc1nc2cnccc2n(CC(=O)Nc2cccc(C)c2C)c1=O
