Task: Answer the multiple choice question.
Question: Which drug has a 8.331\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] COc1ccc(C(=O)c2ccc(OC)c(OC)c2)cc1OC
[b] CCN(CC)C(=O)CN(c1cc(Cl)ccc1OC)S(C)(=O)=O
Answer: b. CCN(CC)C(=O)CN(c1cc(Cl)ccc1OC)S(C)(=O)=O
