Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.849\% 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(C)cc1S(=O)(=O)N1CCN(C(=O)c2ncoc2-c2ccccc2C)CC1
b) CC1CC(NNC(=O)c2ccccc2)=Nc2ccccc2N1C
Answer: b. CC1CC(NNC(=O)c2ccccc2)=Nc2ccccc2N1C
