Task: Answer the multiple-choice question.
Query: Which drug has a 5.786\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C1CSC(c2ccccc2)N1CC(O)c1ccc([N+](=O)[O-])cc1
b: CCC(=O)N(CCN1CCOCC1)Cc1cc2cc3c(cc2nc1Cl)OCO3
c: CC(OC(=O)CNS(=O)(=O)c1ccc(C#N)cc1)C(=O)Nc1cccc(C#N)c1
Answer: a. O=C1CSC(c2ccccc2)N1CC(O)c1ccc([N+](=O)[O-])cc1
