Task: Answer the multiple-choice question.
Question: Which drug exhibits a -5.663% 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] CC1C(=O)Nc2ccc(S(=O)(=O)Nc3ccccc3Br)cc2NC1=O
[b] Br.CC(C)CC(N)C(=O)OCc1ccc([N+](=O)[O-])cc1
Answer: a. CC1C(=O)Nc2ccc(S(=O)(=O)Nc3ccccc3Br)cc2NC1=O
