Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.161\% 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 CCc1cccc(C)c1NC(=O)COC(=O)C1CCN(S(=O)(=O)c2ccccc2)CC1
b CC(C)(C)OC(=O)[C@H](NC(=O)OCc1ccccc1)c1ccccc1
Answer: a. CCc1cccc(C)c1NC(=O)COC(=O)C1CCN(S(=O)(=O)c2ccccc2)CC1
