Task: Answer the multiple choice question.
Query: Which drug has a 7.437\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1cccnc1
b.) CCOC(=O)C(=Cc1cn(C)c2ccc(S(=O)(=O)N(C)C)cc12)C(=O)OCC
c.) CN1C(=O)NC2C1N(S(C)(=O)=O)CCN2S(C)(=O)=O
Answer: a. O=C(NNS(=O)(=O)c1ccccc1[N+](=O)[O-])c1cccnc1
