Task: Answer the multiple choice question.
Query: Which drug has a 24.403% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC1=NN(c2cccc([N+](=O)[O-])c2)C(=O)C1
[b] COc1ccc2cc(C(=O)Nc3c(C)n(C)n(-c4ccccc4)c3=O)sc(=O)c2c1OC
Answer: a. CC1=NN(c2cccc([N+](=O)[O-])c2)C(=O)C1
