Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 13.930\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COc1cccc(NC(=O)CSc2nnc(CNC(=O)c3ccccc3)n2C)c1
b. CC(=O)c1ccc([N+](=O)[O-])cc1
c. CC(C)CCNC(=O)C1CCN(Cc2cccc(OCc3ccccc3)c2)CC1.O=C(O)C(=O)O
Answer: b. CC(=O)c1ccc([N+](=O)[O-])cc1
