Task: Answer the multiple-choice question.
Query: Which drug has a 2.012\% 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: CC(=O)c1cccc(N(CC(=O)Nc2ccc(F)cc2)S(C)(=O)=O)c1
b: COc1ccccc1N1C(=O)c2cccc3c(Cl)ccc(c23)C1=O
Answer: a. CC(=O)c1cccc(N(CC(=O)Nc2ccc(F)cc2)S(C)(=O)=O)c1
