Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.794\% 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) O=C(Nc1c2c(nn1-c1ccc(Cl)cc1)CS(=O)(=O)C2)c1ccccc1
(b) O=C(NCc1ccc(Cl)cc1)c1ccc2c(=O)n(CC3CCCO3)c(=S)[nH]c2c1
Answer: a. O=C(Nc1c2c(nn1-c1ccc(Cl)cc1)CS(=O)(=O)C2)c1ccccc1
