Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.356\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCN1CCOC(CC(=O)Nc2cccc([N+](=O)[O-])c2)C1=O
b) CC(Sc1nc2ccccc2s1)C(=O)Nc1nnc(C(C)C)s1
Answer: a. CCN1CCOC(CC(=O)Nc2cccc([N+](=O)[O-])c2)C1=O
