Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.105\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(O)c1ccccc1-c1nc(-c2ccccc2)c(-c2ccccc2)[nH]1
b CN1CCC(=NNC(=O)CN(c2cccc([N+](=O)[O-])c2)S(=O)(=O)c2ccccc2)CC1
Answer: b. CN1CCC(=NNC(=O)CN(c2cccc([N+](=O)[O-])c2)S(=O)(=O)c2ccccc2)CC1
