Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.179\% 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=S(=O)(Cc1ccccc1)Nc1ccc(F)cc1
b O=C(Nc1ccc(NC(=O)c2ccco2)c(Cl)c1)c1ccccc1
Answer: b. O=C(Nc1ccc(NC(=O)c2ccco2)c(Cl)c1)c1ccccc1
