Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.957\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC1CCN(S(=O)(=O)c2cccc(C(=O)NNC(=O)c3ccco3)c2)CC1
b: O=C1Nc2ccccc2C12NCCc1c2[nH]c2ccccc12
c: CCOc1ccc(NC(=O)CN(C)C(=O)c2cc(-c3ccc(OC)cc3)nc3ccccc23)cc1OCC
d: NS(=O)(=O)c1ccc2nc(NC(=O)c3ccncc3)sc2c1
Answer: d. NS(=O)(=O)c1ccc2nc(NC(=O)c3ccncc3)sc2c1
