Task: Answer the multiple choice question.
Query: Which compound exhibits a -19.807\% 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: CC(=O)Nc1ccc(S(=O)(=O)NCC(=O)OCC(=O)NCc2ccco2)cc1
b: CCOc1ccc2[nH]c3c(NCCO)ncnc3c2c1
c: COc1ccc([N+](=O)[O-])cc1N1C(=O)c2cccnc2C1=O
Answer: a. CC(=O)Nc1ccc(S(=O)(=O)NCC(=O)OCC(=O)NCc2ccco2)cc1
