Task: Answer the multiple choice question.
Query: Which compound exhibits a 22.938% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(=O)c1ccc(S(=O)(=O)Nc2ccc(C(=O)N(C)CC(=O)Nc3cccc(C)c3C)cc2)cc1
b: CCOC(=O)c1c(-c2cccc([N+](=O)[O-])c2)csc1NC(=O)C1CCCCC1
Answer: b. CCOC(=O)c1c(-c2cccc([N+](=O)[O-])c2)csc1NC(=O)C1CCCCC1
