Task: Answer the multiple choice question.
Question: Which drug has a 16.647\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(CNC(=O)c1ccc(Oc2ccccc2)cc1)OCc1ccc(Br)cc1
b O=C(NC1CCN(C(=S)Nc2ccc(Cl)cc2)CC1)C1CCCCC1
c C=CCN1C(=O)C(CC(=O)Nc2ccccc2)SC1=Nc1c(C)n(C)n(-c2ccccc2)c1=O
Answer: b. O=C(NC1CCN(C(=S)Nc2ccc(Cl)cc2)CC1)C1CCCCC1
