Problem statement: Answer the multiple choice question.
Question: Which drug has a 15.387\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CN(Cc1ccccc1)C(=O)CN1C(=O)c2ccc([N+](=O)[O-])cc2C1=O
b: CC(Oc1ccccc1)C(=O)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
Answer: b. CC(Oc1ccccc1)C(=O)NNS(=O)(=O)c1ccc([N+](=O)[O-])cc1
