Task: Answer the multiple choice question.
Question: Which drug has a 7.606\% 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] Cc1c(NC(=O)COC(=O)c2ccccc2Cl)c(=O)n(-c2ccccc2)n1C
[b] O=C(CN(c1ccc(Cl)cc1)S(=O)(=O)c1ccccc1)N1CCN(c2ccccc2)CC1
Answer: b. O=C(CN(c1ccc(Cl)cc1)S(=O)(=O)c1ccccc1)N1CCN(c2ccccc2)CC1
