Task: Answer the multiple choice question.
Question: Which drug has a 12.861\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=S(=O)(c1ccc2c(c1)OCCO2)N1CCN(c2ccccc2)CC1
b) COc1ccc(C)cc1N(CC(=O)Nc1ccc2c(c1)OCCO2)S(C)(=O)=O
Answer: a. O=S(=O)(c1ccc2c(c1)OCCO2)N1CCN(c2ccccc2)CC1
