Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.569% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CN(C)S(=O)(=O)c1cccc(NC(=O)CCc2nc3cc(S(=O)(=O)N4CCOCC4)ccc3n2C)c1
[b] CN(C)C=Nc1ncc2c([nH]c3ccccc32)c1C#N
[c] CCN(CC)c1ccc(NC(=O)c2ccco2)cc1
[d] COc1ccccc1C(=O)OCc1ccc2sc(C)nc2c1
Answer: b. CN(C)C=Nc1ncc2c([nH]c3ccccc32)c1C#N
