Task: Answer the multiple choice question.
Question: Which drug has a -9.164\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(Oc1cccc(NC2=NS(=O)(=O)c3ccccc32)c1)c1cccnc1
(b) O=C(OCc1ccc([N+](=O)[O-])cc1)C1CCN(S(=O)(=O)c2ccccc2)CC1
Answer: b. O=C(OCc1ccc([N+](=O)[O-])cc1)C1CCN(S(=O)(=O)c2ccccc2)CC1
