Task: Answer the MCQ question.
Question: Which drug exhibits a -24.048% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCOC(=O)C1=NNC2(c3ccc(Cl)cc3)C(=O)N(c3ccc(C)cc3)C(=O)C12
b: CC1=Nc2cc([N+](=O)[O-])ccc2NC(C)(C)C1
Answer: b. CC1=Nc2cc([N+](=O)[O-])ccc2NC(C)(C)C1
