Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.600\% 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] COc1ccc(S(=O)(=O)Nc2ccc(C)cc2)cc1OC
[b] CC(=O)Nc1cc(S(=O)(=O)Nc2ccc(C)cc2)c(C)cc1C
Answer: b. CC(=O)Nc1cc(S(=O)(=O)Nc2ccc(C)cc2)c(C)cc1C
