Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.670\% 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] CCOC(=O)c1cncn1[C@@H](C)c1ccccc1
[b] COc1ccc(CNC(=O)CN(Cc2ccco2)C(=O)CCC(=O)Nc2ccccn2)cc1
[c] O=C1c2ccccc2S(=O)(=O)N1CCOc1ccc(F)cc1
[d] C#CCN1C(=O)S/C(=C\c2ccc(-c3ccc(C(=O)O)cc3C)o2)C1=O
Answer: c. O=C1c2ccccc2S(=O)(=O)N1CCOc1ccc(F)cc1
