Task: Answer the multiple choice question.
Query: Which drug has a 0.860\% 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(CN1C(=O)C2C3C=CC(C3)C2C1=O)Nc1nc(-c2ccccn2)cs1
b: CCc1ccc(/C=C2/SC(N3CCOCC3)=NC2=O)cc1
c: CCc1ccc(OCC(=O)NC(NC(=S)Nc2ccccc2C)C(Cl)(Cl)Cl)cc1
Answer: b. CCc1ccc(/C=C2/SC(N3CCOCC3)=NC2=O)cc1
