Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.586\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(COc1ccc([N+](=O)[O-])cc1)NC(C(=O)O)C(O)c1cccc([N+](=O)[O-])c1
b: CC(C)C(NS(=O)(=O)c1cccc(C(F)(F)F)c1)C(=O)N1CCc2ccccc2C1
Answer: a. O=C(COc1ccc([N+](=O)[O-])cc1)NC(C(=O)O)C(O)c1cccc([N+](=O)[O-])c1
