Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.310\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a COc1cccc(/C=N/Nc2ccc([N+](=O)[O-])cc2)c1O
b CC(C)(C)OC(=O)CNC(=O)c1nc[nH]c1C(=O)NCc1ccc(CNC(=O)OC(C)(C)C)cc1
Answer: b. CC(C)(C)OC(=O)CNC(=O)c1nc[nH]c1C(=O)NCc1ccc(CNC(=O)OC(C)(C)C)cc1
